More Information on Maine Green Energy
In Maine, the pine trees use the sun’s energy to grow and flourish, and so can you! Ranking close to the middle for average peak sun hours among US states, Maine, although to the far Northeast of the country, has amazing potential for solar power to flourish and provide the state with renewable and clean electricity so we can all enjoy the natural beauty of the forests and coast line of this wonderful state.
Maine, excluding Alaska of course, is not the northernmost state in the US, although it often tricks the eye in believing it is the way certain maps are drawn, and by the way it sticks out towards the upper right of the country. Maine does however take the award for the Easternmost city in the country – Eastport. So, it’s more than just a clever name. Maine, also being the only US state that is one syllable long, but does better in the category of solar insolation, and has enough peak sun hours throughout the year to make solar power a very legitimate, and growing in popularity, option. Especially, for those summer vacationers who head up to Maine to enjoy the longer days and cozy temperatures off that Atlantic coast.
It is important to remember, if you are looking to install solar panels then you have to understand that not every hour of
sunlight will be converted at the same efficiency ratio. Certain factors such as time of year, the angle of both the sun
and panels, varied cloud coverage, tracking mounts, or if you are using the system year round are just a few of the factors
that could affect efficiency ratios.
Because of this you should look at average of peak hours of sunlight per day, which are the most ideal sunlight hours of solar insolation.
Maine receives an average of 4.51 peak sun hours a day on a fixed solar panel.
