About Us

1. Who is behind this

My name is Vano Gelashvili. I am a full-stack developer and business automation architect — my working life is spent building systems that turn messy inputs into numbers people can act on. You can check that claim: my professional profile is at vanoo.dev and on LinkedIn. Every guide and every calculator on this site is published under my name, on my author page, and reaches me at [email protected].

I want to be equally clear about what I am not. I am not an HVAC engineer, a licensed electrician, or a certified energy auditor. I hold no professional indemnity and I cannot sign off on your installation. If a page here ever reads as though it were written by a credentialed engineer, that is a mistake and I would like to know about it.

2. Why the site exists

Pricing a heat pump and a solar array for my own house, I ran into the same wall everybody does. There is no shortage of writing explaining that the technology is good. There is almost nothing that shows the calculation — the load, the tariff, the capacity factor, the payback period — and what little exists usually sits behind a form that wants a phone number before it will tell you anything.

So the tools came first, and the writing exists to explain the tools. That order matters. The calculators are the thing this site is for; the guides are documentation.

3. What makes the calculators different

• They show the working. Every one prints its intermediate steps, not just a verdict. If you disagree with a number you can see exactly which line produced it.
• They publish their assumptions, including the unflattering ones. Each tool has a section listing what it deliberately leaves out. The solar calculator tells you it ignores inverter replacement; the sizing tool tells you it is not a Manual J.
• They run entirely in your browser. Nothing you type is transmitted, stored or logged. There is no account, no email gate, and no lead capture anywhere on this site.
• They deliver bad news. If your payback runs past the warranty, the tool says so in plain language rather than burying it. An insulation upgrade that will never pay for itself gets told that it will never pay for itself.

4. How the guides are produced

Drafts are researched and written with AI assistance, working from a defined topic brief and a set of reference sources. I review every draft before it is published: checking the calculations, cutting claims that cannot be supported, and rewriting anything that reads as filler.

Two rules are absolute. We do not invent people — no fabricated homeowners, no imaginary case studies presented as real. And we do not claim experience we do not have — nothing on this site says we tested, installed, owned or measured a product, because we have not. Comparisons are desk research against manufacturer datasheets and certification data, and they say so. Where an example is illustrative rather than an actual installation, it is labelled.

The full process is set out in the editorial policy. If you find a page that breaks either rule, tell me and I will fix or remove it.

5. Where the numbers come from

Performance figures, cost ranges, incentive values and efficiency ratings are taken from primary sources rather than secondary reporting: manufacturer technical datasheets and submittal documents; certification bodies such as AHRI, ENERGY STAR and the SRCC; and public datasets and modelling tools from the U.S. Department of Energy, the National Renewable Energy Laboratory and the Energy Information Administration.

Incentive and tariff figures are time-sensitive and jurisdiction-specific. Those get dated and linked to the administering authority, because you should confirm the current position before spending money on the strength of them.

6. How this is paid for

EcoPle is supported by display advertising, and on a small number of clearly marked pages by affiliate links. Advertising is served by third-party networks and is not sold, negotiated or reviewed by me in an editorial capacity. No advertiser or affiliate partner sees an article before publication, and none can commission, approve, alter or withdraw coverage.

Any page carrying affiliate links says so at the top. The battery calculator lists product capacities purely so you can compare against the result; nothing is earned if you buy one of them. When the numbers point at a negative conclusion about a popular product, that is what gets published.

7. Corrections

Corrections are the messages I act on fastest. If a figure here is wrong, send me the page and the specific number — ideally with the source that contradicts it — and I will check it. When you are right, the page is corrected in place and its Last Updated date moves. Nothing gets quietly deleted to make the record look tidier.
