Solar panels depend on sunlight, so the amount they generate will vary with the time of year and weather. In the UK, panels typically produce more in the summer and less in the winter, but they can still generate useful energy on cloudy days. Solar panels work best when they are clean and unobstructed, and shading can reduce output significantly. Most systems also include an inverter to convert the panel output into usable electricity for your home or business.
Solar panels have no moving parts, so they tend to be low maintenance, but they should still be checked periodically to make sure they are secure and operating correctly. Installing panels usually requires a suitable roof or ground space and, in some cases, planning permission. Adding a battery can improve self-consumption by storing excess energy for later use. Solar can reduce electricity bills and carbon emissions, but the exact savings depend on your energy use, system size, and local conditions.
