Is your solar system actually performing?
See what your panels produce against what the sunshine allowed, what they really save on your tariff, and which electricity plan would cost you least. Get an email when something is wrong. No spreadsheets, no guesswork.

Catch problems in days, not months
Monthly totals hide faults behind the weather. Solar Tracking Efficiency checks every day against the sunshine on your panels and tells you when something is off.
- Fault or bad weather? — every day's generation is compared with that day's sunshine on your panels, east/west roofs included, so a dull month never looks like a fault.
- Outage alerts — sunny days far below what the weather allowed (a tripped breaker, an isolator left off, an inverter fault) trigger an email with the energy lost.
- Slow losses caught too — each month is compared with the same month last year, weather accounted for, so a dead string, dirt or new shading gets flagged.
- Never miss an import — a Monday nudge when your inverter data falls behind, and a reminder when your smart-meter file gets old.

Know what your solar is really worth
Batteries and time-of-use tariffs make simple kWh totals misleading. Add your tariff and smart-meter data to see your bill, export credit, savings and payback, bill by bill.
- Your real tariff, half-hour by half-hour — day, night, peak and EV rates, cheap-rate allowances, priced with your ESB Networks smart-meter file.
- Savings you can trust — priced at the times your household used electricity before solar, not "everything at the day rate".
- Estimate vs your real bill — enter each bill and see how close the estimate is, one-off credits included.
- Payback date — what you paid minus grants, how much your savings have recovered, and when the system pays for itself.
- Allowance alerts — an email before you use up the cheap-rate allowance of your billing period.

Find the plan that fits you
Comparison sites guess from an average household. Solar Tracking Efficiency prices every plan on your own last 12 months of half-hourly data, solar and battery included.
- Compare plans on your own data — your last 12 months replayed on every plan, not an "average household" guess.
- Irish plan catalog — suppliers' price pages are checked every day, so price changes are picked up fast.
- Switch in two clicks — apply a plan as your tariff from a date, or use it as the starting point for your own.
- Battery advisor — is charging from the grid at night worth it on this plan, for home use and for export?

How it works
Three steps. Less than five minutes.
Register your system
Size, panels and the way they face, plus your location, so performance is judged against your own weather.
Bring your data
Upload the Sigen app export and your ESB Networks smart-meter file exactly as you download them, or a CSV with years of history.
Track, compare, relax
Performance, costs, savings and plan comparisons update on their own, and you get an email when something needs attention.
Your data, your way
Bring it in without retyping anything, and keep full control of it.
Imports that just work
Sigen app daily exports, ESB Networks 30-minute files and CSVs, uploaded as they are. Days already imported are simply updated.
Battery & grid aware
Grid import, battery charge and discharge, solar to home, battery to grid. Every figure is labelled measured or estimated.
Trends that matter
Daily averages, monthly totals, year-over-year charts and performance against your installer's projection.
Private public links
Share a read-only dashboard with your installer or family using a unique URL. Revoke or rotate it anytime.
GDPR & LGPD compliant
You own your data. Hard-delete your account anytime — no soft delete, no leftovers.
Self-hosted friendly
Open architecture (Laravel + Nuxt + MySQL). Run it yourself or use the hosted version.
Now your AI knows your roof
Connect Claude, ChatGPT, Cursor, or VS Code directly to your solar data through the Model Context Protocol. Ask about performance, bills, plans and your battery in plain language, or log this month's reading, all from the chat window you already use.
ChatGPT signs in via OAuth — no token to paste. The other clients use a personal access token you manage from your profile.
Ask your AI
- "Which plan would have been cheapest for me over the last year?"
- "Was last month a fault or just bad weather?"
- "Should my battery charge from the grid at night on this plan?"
- "When will my system pay for itself?"
- "Am I on track to exceed 1,000 kWh at the EV rate this billing period?"
- "Log March — 612 kWh generated, 480 consumed, 130 exported."
