1. Does the solar installer sell quality products?
To get reliable performance for the long term, it’s a must to invest in quality materials for your solar system. You want a solar installer who will provide you with the best options.
You will hear the term ‘Tier 1’ thrown around. Bloomberg New Energy Finance introduced three tiers for solar panels according to financially based criteria to provide some direction for consumers in understanding the quality of different solar panels. However, the criteria is a broad one so panels that are given Tier 1 status can vary considerably in their quality and performance.
You can therefore choose between a Superior Tier 1 or Basic Tier 1 solar panel. Rule of thumb is a Tier 1 solar panel is in fact the best choice of solar panel however within the tier, there are differences and the one you ultimately choose will depend on the level of quality and performance you require.
