Location and Climate
Location, location, location is important when it comes to solar power production, but it is not necessarily the most important aspect. If you reside in an area such as Hawaii or California, the sun is likely present throughout the day and provides you with the perfect conditions to confidently rely on solar power.
So, what about areas like rainy Vancouver or Seattle? These cities average 1,940 to 2,100 sun hours per year, compared to upwards of 3000 hours for sunnier areas. Sun hours are the number of hours in which the sun is shining. Residents in sunnier climates can reap the benefits of having more sun hours annually, but can also experience a hindrance in their solar panel efficiency if temperatures exceed 35° C. Thankfully for those in the Pacific Northwest, rain is a great way to clean your solar panels and keep them running efficiently.
Fortunately, residents with fewer sun hours can opt for a grid-connected system, with the option of adding battery storage or a backup generator. Regardless of the weather patterns in your area, your solar system should continue to function reliably. Limited sun hours may equate to less power production on solar alone but with grid connection and the proper solar system, you can diversify your energy sources and experience the same confidence as those with longer sun hours. To ensure a solar system is right for you and your home, consult a solar installer in your area to conduct a professional home assessment.
