Solar Energy Can Cut back Your Electrical energy Payments By 90% And Your Carbon Footprint
As environmental concerns continue to grow, more and more of us are adding solar panels to their homes to generate their own electricity.
Solar collectors or photovoltaics (PV) capture solar energy with the help of photovoltaic cells and then convert it into electricity.
How do solar panels work?
Solar PV cells are embedded between layers of semiconducting material, usually silicon. When light shines on them, electrons are released and this creates a flow of electricity.
When solar cells are combined, they form solar panels, while multiple solar panels connected together form a solar system.
To ensure solar panels are exposed to as much light as possible, it is best to install them on top of one South roofEast and west roofs are also suitable.
Solar panels should be placed at an angle in between 10 and 50 degreessit with the optimal angle in between 30 and 40 degrees. You should also make sure there are no buildings or trees nearby that could leave the panels in the shade.
Most solar panels are installed on roofs, but it is also possible to install them on walls, on the floor, or to add solar tiles. Keep in mind, however, that solar tile systems are less inexpensive and typically cost around twice as much as a panel system.
When solar panels are installed, an inverter is also installed to convert the electricity generated from direct current (DC) to alternating current (AC), which is used by most household appliances.
What are the advantages?
The biggest benefit of installing solar panels is that you save electricity costs. If your solar panels are big enough, they can potentially produce enough electricity for your whole house.
You can use the Energy Saving Trust’s solar energy calculator to estimate how much you can save.
Another benefit is that you reduce your carbon footprint. The Energy Saving Trust says a typical household solar system could save about 1.3 to 1.6 tons of carbon per year.
Do solar panels affect the power supply?
If your solar panels are properly assembled, your system should switch seamlessly between using the electricity your solar panels produce and using energy from the national grid when the modules are not producing enough. You won’t notice any difference in your power supply.
You can use your solar panels alongside a normal energy tariff without having to tell your energy company. You only use less electricity from the grid and therefore pay lower bills. However, you should shop around to make sure your tariff is competitive (along with your gas tariff).
What do solar panels cost?
How much you pay to install solar panels depends on the size of your roof and the type of system you choose.
Solar panels aren’t cheap to install, but the cost has come down over the years, and for some people it’s a small price to pay for the environmental benefits it brings.
According to the online service Green Match, one of the most common options is a 4 kW solar panel system, which consists of 16 panels and requires around 29 square meters of roof space. This should generate enough energy for a single family home (three to four people), although you may still need to use electricity from the grid.
The cost of a system of this size is between N2M and N3M. In return, however, you can save around 150,000 N on your annual electricity bill.
A cheaper option is a 3 kW solar panel system, which consists of 12 solar modules and requires around 22 square meters of roof area. The costs are between N1M and N2M, but the savings are also lower at around N 100,000 per year.
How long will it take for the costs to be amortized?
Depending on the size of your solar panel system and the money you’re making from saving monthly utility bills, you can expect to recoup the cost of installing solar panels after 15 to 25 years, according to Green Match.
Larger systems are more expensive, but generate more energy and can save more in the long term. Therefore, a 5 kW solar module could pay for itself after 15 to 20 years, a 4 kW system would take 16 to 22 years and a 3 kW system 21 to 25 years.
What should be considered before choosing solar modules?
When thinking about installing solar panels, you need to consider whether your roof is suitable, whether it is big enough, and how much sunlight it gets.
You also need to think about what size solar panel system you will need.
It’s important to make sure the size is big enough to meet your home’s energy needs, but also that you don’t have a large excess.
You may also want to install a solar battery or energy storage system that will store the electricity generated by your solar panels. In this way you can store the electricity generated during the day to use it at night. In this way, you can become more self-sufficient and use less electricity from the grid.
Although you usually don’t need planning permission to install PV solar panels, you should contact your local authority if you have any restrictions, for example if you live in a listed building or a nature reserve.

How can I get the most out of solar panels?
If you choose to install solar PV modules, read these tips to make sure you get the most out of them:
Use more electricity during the day: Solar panels are most effective in daylight. So remember to do tasks like washing and running the dishwasher during the day, not overnight. If you’re usually out and about during the day, built-in timers for devices can come in handy.
Install a solar battery or energy storage system: As mentioned above, this allows you to store the energy generated during the day for use at night, reducing the need for electricity from the grid.
Reduce waste of energy: Steps like turning off the lights when not in use, taking shorter showers and draft protection in your home will reduce energy consumption.
Keep solar panels clean: It is important that you clean your solar panels regularly. You can purchase cleaning kits for solar panels or install automatic cleaners that are similar to sprinkler systems. Alternatively, you can pay for a cleaning company to do the hard work for you!
