What Are DIY Solar Panels?
DIY solar panels are solar energy systems that you can assemble and install by purchasing kits or supplies from suppliers. DIY solar typically focuses on assembling and integrating systems. These kits typically consist of photovoltaic (PV) cells, mounting hardware, inverters, and wiring instructions. These PV cells convert sunlight into electricity, just like commercial alternatives. You can save money on your electricity bills and reduce your reliance on electricity by generating your own electricity. Doing your own solar installation can also save you thousands of dollars in installation costs.
At the same time, assembling your solar system can be a more complicated process compared to buying pre-made equipment and hiring professionals to install them. DIY solar panels can be a way a good way to offset some of your electricity bills.
Components of a DIY Solar System
A DIY solar power system consists of several basic components. Here is a breakdown of the most important items you will need:
- Solar Panels. These capture sunlight and turn it into electricity. There are different types, such as monocrystalline, polycrystalline, and thin-film solar panels. The more panels you have, the more power they will generate.
- Charge Controller. It regulates the voltage and current flowing from the solar panels to prevent the batteries from overcharging and damaging your batteries.
- Battery Bank (Optional). If you want to store solar energy for use night, you will need a home battery backup system. Common battery types include lead-acid, lithium-ion, and saltwater batteries, so choose based on your needs and budget.
- Inverter. This key component converts DC electricity from your panels or batteries into usable alternating current (AC) that powers your devices.
- Mounting and Racking System. It attaches solar panels to your roof or ground and places them in the best position to maximize sun exposure.
- Disconnect Switches. These are safety devices that allow you to turn the solar panels off from the system for maintenance or in an emergency situation.
How DIY Solar Systems Work
When sunlight hits the solar panels, the PV cells inside them get activated. This creates a DC voltage, which is sent to an inverter. The inverter converts DC into AC electricity – a standard form of electricity used in homes and appliances. With a storage battery, the DC electricity from the solar panel first passes through a charge controller before reaching the battery. It regulates voltage and current and ensures that the batteries are charged without being overcharged.
