Has anyone on Long Island had a solar hot water system installed?

We Answered:

Solar Hot Water systems are not very cost effective, especially so when compared to the lower cost of natural gas hot water heaters. So the cost effectiveness numbers really don't pencil out as a good proposition.
In fact many of these systems become inoperable, and in need of repair, and many of them just get abandoned in place, or removed because they are an eyesore and/ or have lost effectiveness.
