Solar Panels & Arrays

Position your solar panels at an angle equal to your latitude for year-round performance, or adjust seasonally by adding 15 degrees in winter and subtracting 15 degrees in summer to capture maximum sunlight during each season’s sun path. Use a simple angle finder app on your smartphone against the back of your panel to verify…

Match your solar panels to microinverters or power optimizers based on your roof’s shading patterns—even partial shade from a chimney or tree during morning hours means module-level power electronics will recover 15-25% more energy than string inverters lose to the weakest panel. Install power optimizers when you’re working with mixed panel orientations across multiple roof…

Brush snow off your panels with a soft-bristled roof rake from ground level, working gently from bottom to top to avoid scratching the glass or damaging your DIY solar setup. Use lukewarm water in a spray bottle for stubborn ice patches, never hot water that could crack cold panels from thermal shock. Install panels at…

When your solar array needs more power than a simple series connection provides, but your charge controller can’t handle high voltages, series-parallel wiring becomes your solution. This hybrid approach combines the voltage-boosting benefits of series connections with the current-increasing advantages of parallel wiring, giving you the flexibility to match your system’s exact requirements. Most DIYers…

Flip your bifacial solar panels over and you’ll find a second active surface that can boost your system’s energy production by 10-30% – but only if you design your array to take advantage of it. Unlike traditional panels that capture sunlight from one side, bifacial modules harvest energy from both their front and rear surfaces,…
