Facts About Solar Power

With the environment an increasing concern and fossil fuel prices rising, many people are choosing to put solar panels on their home or business. Here are some of the main reasons having a solar system installed makes sense.

The 4 major benefits of installing solar power:

1. Lower electric bills - Sunlight is totally free, so your electric bill will go down when you start relying more on the sun to generate your power.

2. An extra stream of revenue - Thanks to the feed-in tariffs from the government, you can earn money for any electric power you generate, even if you use it.

3. Sales - On days you do generate more electric power than what you use, you can sell that back to the power grid.

4. Reduced carbon footprint - Since solar power is a renewable source of energy that does not release carbon dioxide into the air, you end up reducing your carbon footprint.

Sounds good, so how does it work?

Photovoltaic (also known as PV) solar panels are made of layers of material that are semi-conducting. Silicone is a common material used to make them. Light hitting the cells makes an electric field. The more sunshine that hits the panels, the greater the amount of electricity that is produced.

In order to maximize the amount of solar power collected, PV solar cells are typically installed in groups that are put into panels, which are then installed on top of the roof. The power of solar cells is measured in kWp, which is short for kilowatts peak. This number tells you how quickly it will generate electricity when it is operating at full capacity.

There are other options besides solar panels including solar slates and tiles, which are actual roof tiles that would replace standard roofing rather than simply be placed on top of it. However, solar tile roofs cost about twice the amount of standard solar panel roof systems and our engineers believe that solar panels are better value in the longer term.



The Costs involved in Solar Power

In general the average solar power system runs about 3kWp and is priced around 10,000, which includes VAT at 5%. Residential systems are usually about 3,000 to 3,500 pounds per kWp that is installed, although the price per kWp goes down as the number of kWp goes up.

Every installer has different pricing systems for solar systems, so it is essential that you get quotes from several of them to find out what a fair price really is. Also keep in mind these factors which affect the price of the system you are looking at:

1. Larger systems usually generate more electricity and therefore save more money on your electricity bill.

2. Smaller systems, 4 kWp or less, are not as cost-effective.

3. A PV tile system costs quite a bit more than the standard panel systems, which are about the same price per kWp.

4. Any system that gets built into the roof will cost more than one that simply sits on top of it.

Our aim is to educate users on the benefits of solar power without weighing them down in the engineering aspects (that is what our engineers are there to do). Solar power is an environmental investment for now and the longer-term.

You should ensure that the solar power company who helps you to choose, design and install your system is an expert in this field.
