What to Consider When Purchasing Solar Power Panels?
Cost
The upfront cost of solar panels can be high, which is why many homeowners don’t make the decision to go solar lightly. The Center for Sustainable Energy reports that the average cost of the installation is between $15,000 and $25,000. Polycrystalline solar panels are considered to be the most cost-effective option for solar panel installations, but this depends on the type of panels and the number required for the installation.
While your initial investment in solar panels can be recouped in a few years, it may take longer to recoup your money based on a number of factors, including energy usage and weather conditions; the latter may affect the functionality of your solar panels.
Place
Not surprisingly, solar energy is more efficient where there is more sunlight. For example, residential and commercial buildings in Southern California may benefit more from solar energy than the cloudy Pacific Northwest. Still, even the least sunny places can benefit from solar power, as cooler temperatures will cause solar panels to generate more electricity.
Energy usage
If your energy bills are high, it makes sense to install solar panels to reduce costs and recoup your initial investment over time. However, if your energy usage is minimal, installing solar panels may not be worth the cost. It is also important to note that maximum efficiency is only achieved under optimal conditions, and only at the beginning of the panel’s useful life. As solar panels age and are exposed to harsh environments, their performance will begin to degrade.
