Common mistakes we still see in Massachusetts
One statewide price fantasy; ignoring town permit pace; missing panel upgrades.
Fix: force cash price, force $/W, force model numbers, force exclusions list. If a company will not write those four, leave.
Battery or more panels first?
Extra panels help when you can use or fairly credit the power. A battery helps with outages or weak export value. Price storage alone. Do not let it hide inside a cloudy monthly payment. Related:best home solar batteries · battery backup calculator.
