  2. I was very encouraged to find this site. The reason being that this is such an informative post. I wanted to thank you for this special read of the subject. I definitely savored every little bit of it and I have you bookmarked to check out new stuff you post.

  3. Property value can be increased by the addition of solar panels. According to HUD, for every $1,000 you save in annual utility bills the value of your home rises by $20,000.

In addition to the other benefits, a solar system means a home has a back-up system during electricity blackouts.

  4. It tells you about the wattage of the particular solar electric module. Make sure to check the (warranted) minimum power since the maximum power, stated in Peak Watt (Wp), is always measured under standard test conditions (STC). As you know, nature is not a laboratory. It provides real live conditions and they can differ surprisingly in many ways. Installateur Zonnepanelen Noord-Brabant
