Common Solar panels Questions and Answers

How many solar panels are needed to a powerhouse?
To know how many solar panels you require to power your house you need to, first of all, define your objectives and reasons for the installation of the solar panels from best solar panels. Are you trying to save money you can use to invest in other things or to save as much money as you can? It all depends on your objectives and goals. This will help you come up with clear and concise ideas that will help you in your decision making.
Now calculating how many solar panels you will need will need to be done after taking the following into consideration; the amount of sunlight you receive and the climate; the area where the installation will be done either your rooftop or the space reserved for that; how much electric energy you use; the relative efficiency of the solar panel you are considering to buy and its wattage.


For instance, if there are two very identical houses in the same neighbourhood A and B where A has two occupants who are always busy and rarely stay indoors for long and in B a family of five, B will obviously need more solar panels to sufficiently power the house than A as they consume more energy than the occupants in A. The occupants in A will bare need a solar panels.
The easiest way to go about this is to consult a professional solar installer to do the evaluations for you.
How much does it cost to buy a solar panel?
A lot of people always want to know how much it can cost to buy a solar panel so it will be easy to estimate and calculate the amount needed for their solar project. This depends on several things, first the type of the solar panel in consideration and, the size of the system and the amount the buyer has as leverage.

Let us take this example, as a consumer, you do not have the same relationship with the distributor of the solar panels as a solar installer. So the price the distributor will give the solar installer will be quite lower than the price he will give you. Let us say he gives you a single solar panel at the price of $1 per watt, he will give the same to the installer at about $0.7 per watt. Let us make the sum given you are taking a 200 watts solar panel, the solar panel will cost you $200 while it will cost the installer $140.
If you are looking for the price range of a solar panel then the prices range between $0.8 to $1.25 per watt, outputs between the ranges 150 watts to 350 watts for typical local solar panels. The cost of installation will vary but when working generally with installers from acquisition to installation, it cost less than trying to get a deal maybe online to do it yourself


How long do solar panels last?
One needs quite a hefty upfront cost to invest in solar panels but the best thing is, this pays off in the long run. The monthly bill payments will be avoided meaning more savings plus tax incentives. Solar panels typically have a guarantee of twenty years but in reality, they last far longer than that. Let us look at this little calculation of the efficiency loss of solar panels with time. A solar panels losses 0.5% to 1% efficiency over a period of one year. This means that 25 years from installation it should have lost about 75% to 80% of their rated output. Meaning that to completely exhaust your solar panel it will take you a century or more.

There is a typical standard solar panel warranty of 25 years but some companies even offer more, up to 30 years. Over the life of the warranty of 25 years, for instance, most solar panels are covered to produce a minimum of 80% of their rated output. This is the guarantee given by manufacturers. For instance, a 200-watt solar panel should produce a minimum of 160 watts at the end of the 25-year warranty.
So the question “How long do solar panels last?” has a simple answer, the solar panels can last for a very long time.

How much does it cost to power your house with solar panels?
The rate at which prices of solar panels are falling is making it more possible for lots of people to opt for their installations in their homes. When installed, it is very sure that the monthly bill will drastically be slashed. About some ten years ago, a solar panel system that could sufficiently power a home was as high $50,000.

With new technology now, the price has been more than halved. Nowadays, a 6KW solar power system that can sufficiently power a house may fall in-between $15,000 to $22,000 in taxes exclusive. All of this too will depend on the type you prefer. There are some that cost as little as $2000. You can as well pay for one as high as $50,000.

With the rate at which the price of energy is increasing, going solar could be the next best option. What is certain is that after the hefty upfront required cost, the reward is good.

Solar Basics

How solar works?


1. The photovoltaic
The solar panels are made using unique materials that when heated by a ray of light, the photovoltaic material will convert the energy in the rays of the sun into electricity. Therefore whenever there are sun rays, the solar panel will produce electricity. The island solar grid-tie systems consist of an inverter, switch and a solar panel. The main work of the inverter is to convert the collected dc voltage into an alternating current that will be used by the home appliances such as the radio, Fridge Tv, and many others. The work of the solar panel is to produce the dc voltage and the switch help in closing or opening the circuit. Therefore the flow of the energy is as indicated below. 
A solar panel provides DC (direct current) voltage
• The dc voltage charge the battery 
• DC voltage is put to an inverter to change to ac 
• The AC voltage is then tied to your existing grid 
• The solar energy is now ready for use

That will help you to avoid over-reliance in some other forms of energy sources such as coal-fired electrical power plants.


2. The thermal /hot water systems.
The solar hot water systems use fundamental principle for their working. Since the idea of heating water using the sun has been there for a long time. Only some few improvements have been made to make the solar hot water systems. The solar hot water systems work as follows:
– A fluid that needs to be heated using solar energy is pumped into the solar collectors.
– The solar collectors are painted black for higher heat absorption from the sun.
– When the water or any fluid is passed through the solar collectors, the liquid is heated using the collected heat at the heat exchanger chamber. 
Since now the water/fluid is heated, the liquid is pumped to the hot water system that takes hot water to the washing machine, showers and any other places you want. 

How solar works?

Therefore by considering the above-discussed information about the benefits of solar energy, reasons on why to choose the island solar and the working of the solar panels and the thermal water system. Hence installing solar in your home or place of work can bring incredible benefits.
Thank you.

Some of the benefits of solar energy

The solar energy is an energy that is free from all environmental pollution. Therefore this benefits makes many people prefer it. That is because, during the process of solar harnessing, there is no emission of toxic chemical to the environments. Also, there is no sound pollution since the solar panels do not produce noise as compared to the other forms of energy production, such as the hydro-power stations. Therefore installing solar energy will help you preserve the environment for the future generation.

Reduce energy bills
Another benefit of using solar energy is the ability to reduce the cost of electricity bills. If you choose the island solar business company to install the solar panels in your home or place of work, you will be free from the regular electricity bills. That will help you in improving your savings and also help you to live a more sustainable life.

Solar panels enhance the value of your home
Here applies to economically minded people. By installing the solar panels in your home will help in improving the home value. For instance, if you want to sell a house with installed and fully working solar panels, the price for that home will be higher than that of the home with no solar energy. Hence most of the people who invest in the real estate prefer installing the solar energy in their homes before selling because they know the price of the house gets improved by installing them.

Solar power is easy to maintain
Unlike other energy sources such as the hydroelectric power, the solar maintain cost is relatively small as compared to the different energy production options. To keep the solar energy, one needs minimal maintenance practices such as a soft cloth to clean the solar panels. But to maintain electricity, one needs to pay monthly bills. Therefore by choosing the solar power in your home, you will also avoid the high maintenance cost.

No power blackout
The solar panels are made in a way that they can harness power even when the intensity of the sun rays is very low. That means the solar panels can harness the energy even in rainy seasons or in cloudy weather .therefore by having this source of energy; you will avoid power black which might appear.

Everything You Need to Know About the 5kW Solar System

Solar systems are an excellent source of stable, secure, and reliable energy for all locations, and at all times of the day. Arguably the cleanest form of renewable energy, a solar system can be used to help power a home or business.
The system achieves this through the solar-powered photovoltaic (PV) panels which we see atop buildings. These PV panels take the energy of sunlight and convert it into useful electricity by stimulating electrons in silicon crystals using the photons of light from the sun. For most, beyond just being a clean, green source of electric power, solar systems are the energy source of the future.


The International Energy Agency (IEA) predicts that solar would become the fastest growing renewable energy source. “What we are witnessing is the birth of a new era in solar photovoltaics. We expect that solar PV capacity growth will be higher than any other renewable technology up to 2022,” Dr Fatih Birol, an executive director at IEA said.
That said, if you are looking for a solar power system that can easily compensate for your home’s electricity usage, then you should consider getting a 5kW solar system. This system is the go-to option for most individuals because, among other things, it is cost-effective, performs well in all weather conditions, offers high flexibility, and can easily be expanded.
Now that you know how the 5kW solar power system can benefit you, here are some of the cost and technical information you should be aware of as well:
What is a 5kW Solar Power System?
A 5kW solar system is a power system designed to supply 5,000 watts of DC power. This power system size is ideal for larger homes housing 5 or more people. In other words, the 5kW solar power system is most suited for households that consume around 920kWh of light per month.
While there are other sizes of solar panels, such as the 3Kw one, the 5kW solar panel system is the most common among households and businesses.


How Much Power Does A 5kw Solar System Produce Per Day?
One of the first things homeowners want to know when considering solar systems is the power output, and rightly so. This is because the power output determines how big the system generation is.
With solar systems, the conventional wisdom is that more sunshine equals more electricity. For maximum solar power, therefore, the best direction to face your solar panels would be where they will be exposed to the most sunlight.
Generally, the factors that determine the 5kW solar system output per day include the amount of sunlight the panels are exposed to, the orientation and tilt angle of the solar power generation system, number of daylight hours in your location, the size of the solar panels, sunshine duration, solar intensity, among others.
Thus, the amount of power a solar system will produce equals the output of an inverter multiplied by peak sun hours for your location. Now, assuming you live in a place where the peak sun hours is 5 hours, your 5kW power system will generate 25kW (5 hrs. x 5kW) per day.

Also, note that your solar system will be less efficient if sunlight is blocked by objects such as trees and buildings.

How Much Does It Cost to Install A 5kw Solar System?
Approximately 1 in 5 homes has solar systems installed on their roofs in Australia. The prevalence of solar systems in Australia has been attributed to the significantly lower system prices in the country.
Getting a 5kW solar power system at the right price will be one of the most important decisions you will make since it means you can save tons of money. Knowing the approximate amount to pay for a solar system will help you make an informed decision instead of going in blindly.
In Australia, a 5kW solar system costs approximately $1.26 per watt or $6,800, fully installed. Prices will vary based on your location, components used, and the firm handling the PV system.

Solar system prices are determined by taking into account the roof size and factors that could make the installation process difficult.

How Many Solar Panels Do I Need for A 5kw System?
If you are looking to invest in a 5kW solar system, chances are that you have wondered how many solar panels you will need for your home or business. Since solar panels make electricity generation possible, it is normal that you would want to determine the number of solar panels that will produce enough power to meet your electricity consumption.
These panels help convert sunlight into electric power or heat used to provide electricity. The number of panels you will need depends on the panel size, such as 190W or 250W. So, assuming you use 250W panels along with your 5kW solar system, you will need around 20 panels.
Also, each 250W panel measures about 1.6m x 1m, meaning you will need a minimum of 32m2 of roof space to install them. Once installed, solar panels can last up to 25 years if properly maintained.


However, you will need to take certain precautions to ensure that you are getting solar panels that can last that long as well as those that are right for you. These include:
Check the warranty information: As a home- or business owner who is making a significant investment in solar panels, it is normal that you would want protection in the event your new power source develops a fault. Most solar systems are built with quality craft. Nevertheless, errors happen despite a manufacturer’s best intentions and efforts. So when purchasing solar panels, it is recommended to go for those that offer between 10-20 years’ warranty. Doing so help ensures you are covered for a long time.

Determine the type of panel you want to install: Advances in technology means that there are now several types of solar panels on the market. To make things easier, it is recommended to have an idea of the kind of solar panels you want to install before you proceed to buy. Some of the options available to you include monocrystalline solar panels (Mono-SI), polycrystalline solar panels (p-si), concentrated PV cell (CVP), thin film solar cells, etc. It is advised that you research extensively before you proceed to buy.

Check certifications: Check certifications for the type of testing done on solar panels before you proceed to purchase.
Get recommendation: If you have a friend or family member who is familiar with solar systems, do not hesitate to ask them questions. They will help guide you along.
