What we build
We design calculators and comparison tools around the questions homeowners actually ask: what does solar installation cost, when does solar pay back, how much does battery backup storage add, and what happens when utility rates or incentives change.
Editorial approach
Our content is written to support decisions, not inflate hype. We prefer transparent assumptions, clearly bounded estimates, and direct links between guides and tools so users can test scenarios themselves.
Scope
The site currently focuses on the US. We adapt units, pricing assumptions, and available incentive coverage by state where possible, but every estimate should still be read as a decision support model rather than formal advice.
What we do not do
We do not provide individualized financial advice, installer quotes, battery installation guarantees, or grid interconnection approvals. Where financing, local incentives, or utility tariffs vary heavily by location, we present bounded assumptions and ask readers to validate critical numbers locally.
Editorial Contributors
Our calculators and guides are researched, written, and reviewed by a team focused on renewable energy and financial data:
- Matthew Brow (Lead Editorial Contributor): Matthew is an energy economist specializing in solar energy modeling, utility structures, and solar ROI.
- Nora Patel (Editorial Reviewer): Nora is a quantitative analyst specializing in solar panel degradation, battery storage sizing, and long-term solar panel warranties.
All our models and articles undergo rigorous independent quality reviews before publication.
