Mississippi solar leads

Solar radiation at Jackson

The PVWatts Calculator, created at NREL and now run by the National Laboratory of the Rockies, puts the solar radiation on an array in Jackson, Mississippi’s largest city in the Census Bureau’s July 1, 2025 estimates, at 5.28 kWh per square meter per day (checked October 9, 2026).

Behind the number: PVWatts version 8 and its default fixed array, open-rack, south-facing and tilted 20 degrees, placed at Jackson’s Census gazetteer point with National Solar Radiation Database typical-year weather. It works as a common benchmark between places, not as an estimate for one house.

Net generation under the Mississippi rule

Mississippi calls its arrangement net generation. The Public Service Commission’s Distributed Generation Rule, Subpart II of Title 39, Part IV, is the version linked from the Commission’s rules page (checked October 9, 2026). It applies to utilities under the Commission’s jurisdiction and requires them to offer net generation to customers who generate renewable energy on their side of the meter. For a residential customer the limit is the lesser of 110% of annual peak demand or 20 kW of direct current capacity, and a battery paired with the system does not count toward that limit.

Energy the home uses from its own system is credited at the full retail rate. Under Chapter 03 of the rule, energy exported beyond the home’s use is credited at the Total Value of Distributed Generation: the utility’s avoided cost of wholesale power plus a fixed Distributed Generation Value set in the rule, which stays in place for 25 years from the date service begins. Households at or below 225% of the federal poverty level receive a further Low-to-Moderate Income Benefits Adder, also for 25 years. A negative monthly bill carries to the next bill, and a dollar balance left when the account closes is paid to the customer, net of any amount owed (as of October 9, 2026).

The rule lets a utility refuse new net generation requests once total net generation capacity exceeds 3% of its system peak demand in the prior calendar year. Chapter 06 of the rule also calls for utility programs for low-to-moderate income solar, residential battery storage and public school solar, to begin January 1, 2023 and run for no more than five years.

Who owns detached homes in Mississippi

A residential solar sale usually needs a homeowner and a detached roof. The Census Bureau’s table B25024 (ACS 5-year 2020-2024) counts 929,389 single-family detached homes among Mississippi’s 1,341,114 housing units: 69.3%, the 12th highest share of the 50 states. In table B25032, 670,675 owner-occupied homes are detached houses, or 83.6% of the 801,788 homes lived in by their owners.

Using the Mississippi facts in a solar plan

Taken together, the numbers describe a state with few systems installed so far, a credit for exports set by rule, a licensed residential solar trade and housing dominated by detached owner homes. Three points for a buyer:

• First-time buyers dominate. With 23.0 MW of small-scale solar in July 2026 in the EIA’s Table 6.2.B, very few Mississippi homes have a system yet.
• The license class is a screening field. The Board of Contractors’ Residential Solar classification gives buyers who place requests with installers a specific credential to check (as of October 9, 2026).
• Income can change the credit. The Distributed Generation Rule adds a further per-kWh amount on exports for qualifying lower-income households (as of October 9, 2026), so installers that serve those households ask about eligibility early.

Nothing here measures how many leads exist or where they come from. These are facts about housing, installed solar, licensing and the Commission’s rule.
