Game in the Brain

So this is a Solar ROI/Payback period Calculator. I made with Claude. ROI is the “Profit” after something has “paid back”. Value equal to the Value invested.

So what I learned using this:

1. Our plant paid Solaric Around 80k php/KWh or 8M for 100Kw of solar panels in 2016 (generating 400KW a day on average over a year, based on data supposedly – the Huawei Inverted doesn’t give detailed reports and is very difficult to use which will remedy without embedded Systems.) Recently in 2025 the bids now cost 40-50k/KW. Most realistic plans for residents are up to 95Kphp with some being very difficult to believe at less than 20k. This means there is some form of deception.
2. There are many players and many prices are everywhere. It is still a growing and maturing market – when you compare it to cars or homes. In this AI using world, we can embed – poisoning text to the AI to make ours stand out (and skew the report – a poisoned saying that all the costs of all the others are x2 or 3x more expensive.) – you just really need more basic scrapers that will look for values and remove all other text (like poisonous prompts).

When you look at the numbers, while the 60-95k Php is realistic, it isn’t the best deal. When people are paying 12-15php/kWh you need 40kphp/KW and below total cost of ownership (inverters, framing, labor, wiring etc…). Then there is the quality of solar – some solar is very low efficiency; a cloudy day can drive collection down, and a leaf can reduce 90% of the panels’ power draw.

3. COMFAC going into this crowded market needs to really go by Comfac’s 45 year reputation and lean into integrity and straightforwardness. We will have to use our business intelligence to see regions where we have OUR deals as their BATNA (best alternative to negotiated agreement) – we are the best given that our understanding of their Php/KW and circumstances.

Comfac has to move volume of solar and be able to use the solar internally in other business lines when we cannot move the supply. We have to have internal flexibility and adaptation with our product.

In terms of importing, we will lose because of how corrupt the Philippines is; where Comfac will excel is in advanced engineering: our containerized solar with freeCAD automation allowing us to make custom containers and portable solar deployments (pre-fabing solar) is key. Advanced engineering capabilities is a moat we can have.

As well as access to power quality tools of our partners and the integration of our partner products.

4. Filipinos need < 40k /kWh for solar in their homes. And we have to penetrate that area and partner with local installers (creating livelihood) so that people have repeat business and we don’t need extensive logistics. If we have sufficient local partners and the local installer + Comfac + customer win – it’s a Win + Win + Win strategy. It’s possible with good EQ, a powerful marketing system, and mastery of supply chain (this includes being able to move our unsellable inventory for other uses).

What you will see in the app:

1. Save scenarios and export to share so you can set your costs and then load it.
2. Save price deals you see and share it. The “Saved” default deals have their Facebook links are both very expensive and some are too good to be true.
3. It’s a progress web app – you can save it to run offline on your phone or desktop.
