Why solar quotes vary so much between companies

We've seen thousands of reviews where homeowners felt misled about solar costs. The most common complaints: quotes that didn't include all fees, unexpected permit costs, and "after" prices that didn't match the sales pitch. At Modern Electric, we show you everything upfront - equipment, labor, permits, interconnection. What you see is what you pay.

Why is solar installation so expensive?

Your roof's age and condition can add costs if repairs are needed first. System size is the biggest factor. More panels = higher cost, but also more savings. Roof type matters. Tile or metal costs more to install than composite shingle.

The 30% federal tax credit is the big one. On a $30,931 system, that's $9,279 back. Texas also exempts solar from property taxes.
