Estimates, not guarantees

Every result — savings, battery size, NPV, IRR, payback — is computed from the meter data, bills, tariffs, prices and assumptions that went into it, and is only as good as they are. A future year will not be the same as the past one. Results are not a bankable guarantee of savings or performance.

Every saving Zorowatt reports is computed by its own bill engine from those inputs, so the arithmetic can be followed and checked.

Not advice

Nothing on zorowatt.com or in a Zorowatt report is investment, financial, tax, legal or engineering advice. Zorowatt is not a licensed adviser. Get advice from a qualified professional before an investment decision.

Tariffs, prices and product data

Tariffs, grid charges, subsidies and market prices change. Zorowatt keeps each tariff versioned, with its source and the date it was read, but cannot promise that a tariff is current, complete or applies to a given site.

Battery specifications and prices in the battery database come from public sources, each shown with its source and the day it was read. They can be wrong or out of date; the manufacturer's current data sheet and a quote decide.

What Zorowatt does not do

Zorowatt does not control batteries or any other equipment, does not trade energy, and does not design electrical protection, grid connections or installations. It does not replace a grid operator's connection study or an installer's design.

The free tools

The free calculators give a quick first estimate from a few numbers. They are simpler than a full site analysis and are meant for a first look, not for a decision.

Your responsibility

If you present a Zorowatt result to a client, you are responsible for checking it and for what you tell them.
