Solar power is one of the most popular renewable energy sources. Compared to other forms of renewable energy, solar power is cheap and easy to install. In the excerpt below, you will learn the various considerations you should make when installing a solar power system.
You will require the following:
1. Solar Panel
The solar panel is a glass-like structure that houses photovoltaic cells that convert light into electricity. Here are some tips to help you choose a suitable solar panel for your home:
- Go for reputable manufacturers that provide guarantees and warranties. Choose a panel with a twenty-year guarantee.
- The nameplate rating refers to the amount of electricity the panel will generate. For instance, a 300-watt solar panel produces more power than a 200-watt panel.
- If you live in an area with strong winds, hailstones, or snow, go for a solar panel whose glass casing is strengthened to withstand such conditions.
- The efficiency rating refers to how effective the panel converts light into electricity; the higher the rating, the better the panel.
- The temperature coefficient is the efficiency lost when temperatures exceed 25℃. People that live in hot climates should purchase solar panels with a low temperature coefficient.
One of your primary concerns when purchasing a battery for your renewable energy project should be its storage capacity. A battery with a high storage capacity (measured in kW/h) will last for long before requiring a recharge. These batteries are ideal if you intend to use the solar power system as the primary source of power in your home. Check the battery's warranty. A battery with many charging cycles will last for long.
Deep-cycle, lead-acid batteries and lithium-ion batteries are ideal for solar power plants.
The inverter converts direct current (DC) into alternating current (AC). String inverters are cheap and ideal for most home applications. Module-level power electronics (MLPE) inverters are expensive and highly efficient. They are your best bet if the solar panel has limited access to sunlight.
The following are some solar power system installation tips:
- Ask an experienced and licenced professional to help you install the system.
- The solar panel should be installed in an area with no shade and direct access to sunlight. Typically, if you live in the northern hemisphere, the solar panel should face the south.
- Use high-quality, weather-resistant wiring during installation.
- If the system produces too much power, you could sell some to the national grid.
