Solar Panel Installer FAQs

what are solar panels made of?

Solar cells , also referred to as photovoltaic cells (PV), absorbs energy from the sun and converts it to generate electricity. This, however, should not be confused with photovoltaic thermal cells or PVT which operates to generate heat for water in homes. Solar cells are linked electrically and also carefully organized into a large frame which is popularly called solar panels. Generally, solar cells are produced or made of silicon semi conductors which works to absorb sunlight and then turn it into electricity for use at a home. A solar panel comprises of either 60 or 72 solar cells which are electrically interconnected in series and parallel and also positioned in between glass and plastic which is then framed.

At present, solar panels incorporated for residential or domestic purposes only possesses the capacity to make use of only about 20 percent of the sunlight they’re able to absorb and convert it to electricity - also called solar efficiency. Available in the market are also a wide range of solar cell available for both industrial and commercial purposes. This type of solar panels have an efficiency rating of about 40 percent which will also automatically make them more costly than the domestic types.

One great thing about the solar industry is the fact that it keeps improving in such a way that raises both its efficiency as well as overall quality. And with further research and development, this is expected to even increase as the years go by. What’s more? As these aspects keep rising, it’s also expected that the solar panels price should be on a decrease. That way, they’ll become available to a wider range of individuals who’ll also like to save money on electricity bills and go greener.

As a result, it’s important to avoid connecting solar photo voltaic modules directly to your better, if you don’t want it damaged. To control the current received from the solar panels, the charge controller is required. It has three connecting points - one for the battery, one for the solar panels and the last for Direct Current (DC) identify the one for solar panels and connect accordingly.

✓ They can help you save about 600kg of carbon dioxide emissions on an annual basis.

is solar thermal cost effective?

If you’re looking to install a solar thermal system in your home, this is usually one of the first concerns several homeowners have. Being fully aware that solar water heating systems are usually more expensive than their counterparts - the conventional water heating systems, the question arises whether or not you’ll be able to save some money from your solar water heating system in the long run. In this article, we aim provide an answer to this important question. Let’s take a closer look!

When it comes to solar thermal systems, the money you’ll be able to save in the long run depends on a wide range of factors. These factor includes:

✓ Your system’s performance.

✓ Your geographical location and solar resource

✓ Your household’s hot water demand

✓ Financing and incentive options that are available.

✓ The cost of fuel that’s being used for your alternative or backup water heating system, if you own one.

✓ The cost of conventional fuels such as oil, electricity or natural gas.

There are several benefits, however, that comes with the installation of a solar water heating system. Since the sun is absolutely free, future fuel shortages and price hikes will have little impact on you. Also, on the average if you decide to fit a solar thermal system your water heating bills is expected to drop about 50 percent to 80 percent. What’s more? The economics are even a lot more attractive when you’re just about to build a new home or refinancing. When you include the price of a solar water system in a 30 year mortgage, it’ll normally amount to very low price per month. Therefore, on a monthly basis you’ll be saving more and paying less.

Does solar thermal generate electricity?

No – solar thermal doesn’t generate electricity. Unlike solar PV, solar thermal panels harness the sun’s energy and convert it into heat which is then transferred into your home.

You can have evacuated tube solar thermal panels or flat plate collectors; evacuated tubes are thought to be more efficient that flat plate collectors. They both work by using the sun’s rays to heat a transfer fluid, usually made from water and a type of antifreeze, which is pumped to a heat exchanger inside a water tank in your home. The heat from the exchanger heats the water inside your tank, then when the liquid releases its heat it’s transferred back to the collectors to start the whole process again.

You’ll need to use your solar thermal panel system with a boiler, collector or immersion heater. This is so that the water can be stored and used for your hot water and heating, and also because in the UK, people generally need to rely on another source of heating in the winter. There are fewer sunlight hours in the winter months, so it’s not often possible for solar thermal panels to generate enough heat from the sun to get your water up to temperature.

Whatever the time of year it is, you might want to heat the water up further than your solar panels can manage. That’s why you’ll still need a form of traditional hot water heating, but you should see savings on your energy bills. If you’re currently using natural gas, you can expect savings of around £60 per year on your fuel bills, while if you’re using LPG it could be as high as £100 pr year
