We use only the highest efficiency and highest quality LG 335w - 400w and SolarWorld 295w - 345w modules.
The difference between the highest quality and the lowest quality modules is a few pennies per watt in system cost, but the difference in utility cost savings is much greater over time. Why would you want anything but the best?
The solar industry is in extreme competition with narrow margins. Companies cut corners in workmanship quality and balance of system, to match lowest bids, while salespeople oversize systems to maximize commissions. Whether you buy too much, or compromise the waterproofing to get to the lowest cost/watt, either way, you're all wet. Makello has a better way.
Below are 4 topics to teach you how unethical solar installers can cut-corners where the homeowner and the permit inspector won't see it, in order to lower the bid price.
Poor quality installation techniques can only save money in the short term. Eventually, the home repairs for potential water leak damage will outweigh any cost savings.
How does a homeowner build superior quality workmanship into the solar panel bidding process, to protect the home from the risk of water leak, accidental injury, electrical shock and fire hazards?
Makello documents the site survey and installation techniques with step by step photos and videos. Proof of quality workmanship is a "Buyer's Right".
Can you name any electrical appliance, other than solar panels, that can work uninterrupted, for 30 years or longer?
Long term power production and cost savings is only part of the bigger picture. For example, how much do you save with solar if a poor quality installation causes a roof leak?
