For both industrial and domestic power consumption, solar energy is becoming more popular as an alternative energy solution. Since the introduction of solar panels, there has been a reduction in over-dependence on fossil fuels (which are skyrocketing in cost by day). Solar energy is renewable and requires little or no major maintenance. Additionally, zero greenhouse gas emission makes solar energy an Eco-friendly choice of energy. If you are a homeowner and wish to profit from the many benefits of solar energy, this article helps you learn more about solar panels. From installation to having a solar power system that works for years to come.
There are different types of solar panels in the market, each with unique features, pros, and cons. For instance, monocrystalline solar panels have a high-efficiency rate, high lifetime value, and are optimized for commercial spaces. Polycrystalline panels, on the other hand, are also sensitive to high temperatures and take up less space which makes them ideal for residential use. The latter is lower in price but also have a lower lifespan compared to monocrystalline panels. Basically, your choice of solar panels will ultimately depend on the availability of space, your preference on type and how much you’re willing to spend. Monocrystalline, polycrystalline and amorphous silicon solar panels is the respective order from the most expensive to the least expensive solar panels. Before purchasing solar panels consulting an experienced roofer can go a long way to getting you started.
These are the basic qualities of a great roof ideal for a solar panel installation:
Asphalt shingles, clay tiles, and standing metal roofs are easier to work with hence make the best roofing materials for solar panels installation.
The roof should be in good condition and not scheduled for repairs.
Pitched or sloping roofs are the best for solar panels installation. A power generation angle of 30-40 degrees is ideal in most places. When working with flat or awkward-angled roofs, roofing contractors will install brackets or special racking at an extra cost.
During the actual installation, a roofer will visit the site to assess the roof type, shading, roof angle, and the available space. Later, preparation of the roof will involve roof adjusting loose tiles or shingles and removing any debris. The process also involves linking electrical wiring connection and solar panels to the power system. Next is fixing racking systems to help anchor solar panels. The last step in the process is installing an inverter whose work is to convert direct current (DC) to alternating current (AC). Depending on the complexity and size of solar panels, this whole process can take about three days.
After installation, you will need to keep inspecting the panels for pilings and accumulated dirt. You see, solar panels have an upward angle which makes them prone to a buildup of dust and bird droppings. When dirt accumulates on the panels, it slows power generation. Light films of dirt may benefit from moderate rain but a thicker film of accumulated dirt will not wash off easily. To remove accumulated dirt, it’s important to give your solar panels a thorough cleaning the right way.
The initial cost of installing solar panels may be high, but in the long-term, it all begins to make sense once you notice the significant reduction on your electricity bills.
