Solar Panels

Snow White Electricians enlists the services of certified solar panel technicians to provide a full range of services, from solar panel installation, maintenance, upgrades, and even EV charging.

Solar Panels are a popular addition to every modern home. The main reason to have them installed is the significant reduction in energy bills. Although still expensive, they provide a good term for the return on investments. Along with the reduced bills, they reduce the household's carbon footprint, improve the house's value, and provide independence from the electric grid. Many families use their solar panels to earn money from the SRECs and take advantage of incentive programs.

Monocrystalline solar panels
Also popular as single-crystal panels, they are made from a single silicon crystal, which also gives them their black color. The pure silicon crystal makes them the most space-efficient and the longest lasting. However, they are also the most expensive.

Thin-film solar panels
These panels are very lightweight due to their fine thin-film covering. This covering removes the need for a frame and makes them very variable in size to suit specific needs.
There are three types of thin-film solar panels
● Cadmium telluride (CdTe)
● Amorphous silicon (a-Si)
● Copper indium gallium selenide (CIGS)


Polycrystalline solar panels
Multiple silicon crystals are melted to produce this type of panel. This makes these solar panels much cheaper but less energy effective. They also have lower heat tolerance.

Passivated Emitter and Rear Cell (PERC) panels
PERC solar panels are considered an upgrade to the two above due to the preservation layer added to the rear surface of the cell.
The layer is used to reflect light back into the cell, reduce the tendency of the electrons to recombine, and allow greater wavelengths to be reflected, increasing the panel's efficiency in all three cases.

Solar Panel Installation
Snow White Electricians is a certified solar panel installer (повече информация за сертификата, който притежават).
Solar Panel installation
SW Electricians follows the standard procedure to install solar panels. It is the same for both domestic and commercial solar panels.
- Set Up Scaffolding
- Install Solar Panel Mounts
- Install the Solar Panels
- Wire the Solar Panels
- Install Solar Inverter
- Bond Solar Inverter and Solar Battery
- Connect the Inverter to the Consumer Unit
- Start and Test Solar Panels

There are four types of solar panels, and Snow White has them all covered:

Differences between domestic and commercial solar panel systems

● Efficiency – commercial solar panels are more efficient by about 2%
● Size – commercial panels are far bigger in size. The average domestic panel is 65 inches by 39 inches and has 72 cells. The commercial one usually has 96 cells and is 78 inches by 39 inches.
● Installation – both are installed by bolted racking system. Both systems can take up to a month to compete. Commercial panels are usually easier to install because commercial buildings generally have flat roofs.

Maintenance and service

SW Electricians provide a full range of services and maintenance of your solar panels.
Solar panels do not require much maintenance because of the lack of moving parts. They need to be inspected every couple of years and cleaned every few months (информация за гаранцията и дали пада при почистване).
The installer should inspect your solar panels every four years. Common problems with domestic and commercial solar panels include:
● Cracks and hot spots
● Potential induced degradation (PID)
● Loose Wiring
● Inner module damage
● Module Damages Caused by External Factors
