Install Solar Panels
The most exciting step: harnessing the power of the sun!
- Mounting System: Invest in a sturdy racking system. Given that it bears the weight of the panels, often for decades, skimping here can be a costly mistake. There are fixed mounts, but adjustable mounts allow changing the panel's inclination based on the season, optimizing energy capture.
- Panel Direction: The general thumb rule is: The general thumb rule is: Northern Hemisphere: Panels should predominantly face south to capture the maximum sunlight. Southern Hemisphere: Aim for a northern orientation.
- Angle of Inclination: The tilt angle is crucial. It should ideally equal your latitude, but slight adjustments can be made seasonally for better efficiency. During winter, a steeper angle helps capture the lower sun, while in summer, a flatter angle is beneficial.
Set Up the Electrical System
Electrical setup demands precision and caution.
Opt for high-quality, UV-resistant wires, especially for connections outside the workshop. Properly insulating them prevents potential shorts and reduces the risk of fires.
Connect the Inverter
- Location: Your inverter should be placed in a cool, dry spot. Overheating reduces efficiency and can even damage the inverter. While garages or basements are commonly chosen, ensure the place is free from excessive dust or moisture.
- Distance: Ideally, the inverter should be as close as possible to the solar panels to minimize energy loss in transit. However, balance this with the need for a cool location, as discussed above.
- Ventilation: Batteries, especially lead-acid ones, can release gases. Therefore, they should be in well-ventilated areas.
- Protection: Shield the batteries from direct sunlight. Excessive heat can reduce battery life and efficiency. Moreover, a cool, consistent temperature helps in maintaining optimal battery performance.
