How Much Power You Use Daily

Why is this important? The price of most solar equipment (including solar panels) is decided based on their respective power ratings, also explained as the amount of solar power it can generate per hour. If your power needs are low, you can shed off a few bucks on the cost of solar equipment.

The Type of Solar Power System

Yet another important factor that decides the cost of solar panels for a 1500 sq ft home is the kind of solar panels you are considering to begin with. Here’s a look at the different solar power systems available at your disposal:

Grid-Tied System

Grid-Tied With Battery

So picture this: you can draw ample power from the grid and feed power back into the said grid for debates, store the power for use at your convenience, or supply the power to your house directly.

This one happens to be a little more expensive than the straightforward grid-tied systems, but nothing unachievable.  

Off-Grid System
