Across the world, governments are encouraging households to install solar panels, battery storage, and in some cases, go fully off-grid. Here’s a detailed look at current rebates, incentives, and programs you’ll find around the world in 2025.
Australia
Australia leads with strong national and state programs supporting both grid-tied and off-grid solar.
Federal Incentives
Small-scale Renewable Energy Scheme (SRES): Eligible solar and battery systems create Small-scale Technology Certificates (STCs), delivering an upfront discount.
A typical 6.6kW solar system might attract $2,400–$3,000 worth of STCs.
Off-grid systems fully qualify for STCs, giving rural households the same benefits as grid-connected homes.
State Incentives
Victoria – Solar Homes Program:
Solar panel rebate up to $1,400.
Battery rebate up to $3,500.
0% interest loans up to $8,800 for solar and up to $14,000 for batteries.
Available for existing homes, new builds, and rental properties under certain conditions.
NSW – Empowering Homes Program:
Up to $14,000 interest-free loans for solar and battery installs in selected postcodes.
Queensland – Home Energy Upgrades:
$3,000 rebate for new solar systems and another $3,000 for battery storage, targeting low- and middle-income households.
ACT – Sustainable Household Scheme:
0% interest loans up to $15,000 for solar panels, batteries, or combined systems.
Northern Territory – Solar Energy Transformation Program (SETuP) and Home Battery Scheme (closed 2023):
Rebates of up to $6,000 for batteries were available; some interest-free finance options remain through local banks.
Off-Grid Support
Federal STCs: Off-grid systems still claim STCs based on expected generation over 15 years.
Remote Area Energy Support: Some regional councils and programs (e.g., Remote Power Systems Program WA) offer top-ups for truly remote installations.
United States
American homeowners benefit from strong federal tax credits and state-specific programs, many of which support batteries and off-grid systems too.
Federal Incentives
Investment Tax Credit (ITC):
30% of total installed cost credited back through your tax return.
Applies to both solar PV and battery systems (battery must have ≥3kWh capacity).
Residential Clean Energy Credit (Inflation Reduction Act, 2022):
Covers standalone battery storage, even without solar panels, provided 100% renewable charging.
State and Local Programs
California – Self-Generation Incentive Program (SGIP):
Battery rebate between $150 and $1,000 per kWh installed, depending on household income and grid vulnerability.
New York – NY-Sun Program:
Up to $1,000/kW rebate for solar systems, plus additional $250/kW if paired with batteries.
Low-income households qualify for larger rebates under the Affordable Solar Program.
Massachusetts – SMART Program:
Fixed tariff payments for solar energy production, with additional incentives for battery-paired systems.
Nevada and Maryland: Offer separate solar tax credits (e.g., 40% state tax deduction in Nevada up to $10,000).
Net Metering Policies: Offered in over 30 states, though evolving (e.g., California’s NEM 3.0 shifts to time-of-export pricing).
Off-Grid Support
USDA REAP Grants:
Up to 50% funding for renewable energy projects in rural areas, including off-grid homes.
ITC for Off-Grid Systems:
Full 30% tax credit applies to off-grid solar+battery setups.
Europe
European countries tend to favour tax deductions, zero VAT, feed-in tariffs, and battery grants.
Germany
KfW 270 and 275 Loans:
Government-backed low-interest loans for solar PV systems and batteries.
Up to 100% of project costs covered under certain conditions.
VAT Refunds:
0% VAT on new residential solar installations introduced from 2023.
Self-Consumption Exemptions:
No grid surcharges for owners using ≤30kW systems primarily for self-use.
United Kingdom
Zero VAT: Residential solar and battery systems are VAT-free until at least March 2027.
Smart Export Guarantee (SEG):
Requires large electricity suppliers to pay homeowners for excess solar exported back to the grid.
Export rates typically range from 5p–10p per kWh.
Local Council Schemes:
Some councils and energy suppliers offer small grants or free assessments.
France
CITE (Tax Credit for Energy Transition):
15% tax credit on eligible PV costs up to €600, phased out into MaPrimeRénov in some areas.

Africa and Asia have strong off-grid program support but fewer direct rebates for general households.
Off-Grid Solar Incentive Support (2025)
If you’re planning to go fully off-grid, the best support comes from the USA and Australia. Both countries offer strong financial incentives, including tax credits, rebates, and grants that apply equally to off-grid homes. India and Africa also provide substantial backing, mainly through government and donor-funded programs aimed at rural energy access. In Europe, most incentives focus on grid-connected systems, with very limited formal support for residential off-grid projects.
Choosing the right location — and matching your system to available incentives — can make off-grid living more achievable and affordable than ever before.
