How it works Remote systems are easy to neglect. The annual maintenance cost estimator in our Maintenance & Lifespan section can help you budget for the maintenance that keeps output from slipping.

See whether sourcing parts separately actually saves meaningful money.

Understanding kit vs DIY pricing

The direct answer for a typical mid-size system

For a 2,000-watt system, a budget kit costs around $2,200 while assembling matching panels and a charge controller separately costs about $2,150, only a 2% difference. At this price gap, kit convenience and bundled warranty coverage often outweigh the small potential savings from sourcing parts individually. Pair this with the federal ITC calculator to see the full picture before you commit.

What separates the three kit tiers

Budget kits typically use lower-tier panel brands and basic mounting hardware, mid-range kits offer better-known brands with improved warranties, and premium kits include top-tier panels, sturdier components, and longer warranty coverage, with price scaling accordingly from roughly $1.10 to $1.90 per watt. The right tier for you depends on how much you value brand reputation and warranty length against a straightforward budget-tier system that still does the job. Current figures live on the EIA's Electric Power Annual report, which updates them when the program changes.

Why kits and DIY costs land so close together

Kit manufacturers buy components in bulk and pass some of that savings on to the buyer, offsetting much of what a DIY buyer might otherwise save by sourcing parts individually from separate suppliers. The remaining price gap is often small enough that convenience, matched and pre-tested components, and a single warranty point of contact become more meaningful factors in the decision than raw cost alone.

What this comparison doesn't include

This comparison covers panels and charge controller only, matching what most base-tier kits include as their core offering. Battery and inverter costs vary significantly by chemistry and brand and are usually priced and purchased separately even when buying a panel kit, so add those costs on top using a dedicated full system cost estimate for a true total. DOE's solar photovoltaic technology basics is a useful primer if you're still deciding which components actually belong in your build.

What to check for the full picture

Add batteries and inverters on top of whichever panel option you choose with the off grid system total cost estimator, and confirm your target system wattage with the off grid panel count calculator if that number is still open. If financing the purchase is part of the plan, the financing cost per watt calculator in our financing tools translates these per-watt prices into a monthly payment figure, and the federal ITC calculator in our rebates and incentives tools shows how a tax credit changes the real cost either way. Broader electricity cost trends referenced throughout come from EIA's Electric Power Annual report.
