## Description

This MCP gives you a full technical and financial assessment for residential solar power. It stops you from having to juggle complex spreadsheets just trying to figure out how much roof space you need or if the investment will actually pay off. You start by feeding in your annual energy usage and local sun hours, letting the system determine the necessary capacity. After that, you can run deep dives into economics—checking things like payback periods over 25 years and comparing financing models (Purchase vs. Lease). Furthermore, it quantifies your positive environmental impact so you know exactly what carbon offset potential you're getting. Because Vinkius hosts this MCP, you connect once to your preferred AI client and gain access to all these detailed energy calculations.

## Tools

### calculate_financial_returns
Calculates the detailed financial payback period and total savings projections from a solar investment.

### compare_financing_models
Evaluates the net cost difference between purchasing, leasing, or using a PPA for a solar setup.

### estimate_environmental_impact
Quantifies your annual carbon offset potential by calculating avoided emissions.

### estimate_system_capacity
Determines the precise required kilowatt (kW) capacity for a solar system based on usage and sun hours.

## Prompt Examples

**Prompt:** 
```
I'm looking at 10kW systems. How does buying it versus using a PPA affect my total cost over 25 years?
```

**Response:** 
```
**Solar Financing Comparison**

| Model | Upfront Cost (Approx) | Monthly Payment | Total Net Cost (25 Yrs) |
| :--- | :---: | :---: | :---: |
| Purchase | $20,000 | N/A | **$18,500** |
| PPA | $0 | $150 | **$36,000** |

*The purchase model is cheaper long-term. Note that the PPA gives you zero upfront risk.*
```

**Prompt:** 
```
My energy usage increased last year to 14,500 kWh annually. What system size do I need now?
```

**Response:** 
```
**System Capacity Estimate**

Based on your updated annual usage of 14,500 kWh and assuming a local peak sun hour average of 5 hours: 

The required solar capacity is approximately **10.2 kW**. This size accounts for standard efficiency losses and maximizes energy generation based on your consumption profile.
```

**Prompt:** 
```
What does the environmental impact look like if I go with this system?
```

**Response:** 
```
**Carbon Offset Projection**

Installing a 10.2 kW system will generate significant clean power, resulting in these estimated annual offsets:
*   **Annual CO₂ Avoided:** 7.8 metric tons
*   **Equivalent to:** Removing an average car from the road for approximately 6 months.

This provides a clear sustainability benefit alongside your financial savings.
```

## Capabilities

### Determine optimal system size
It calculates the precise kilowatt (kW) capacity needed for your home based on your annual energy consumption and local sun exposure.

### Analyze investment returns
The tool provides detailed financial projections, estimating savings, payback periods, and total long-term value over decades.

### Compare financing options
It evaluates the costs associated with different ownership structures, including purchasing, leasing, or using a Power Purchase Agreement (PPA).

### Measure environmental benefit
The system quantifies your personal carbon offset potential by tracking how much pollution you avoid annually.

## Use Cases

### Figuring out if solar is even possible
A homeowner asks their agent: 'Based on my 12,000 kWh annual usage and 5 peak sun hours, what size system do I need?' The agent uses `estimate_system_capacity` to immediately give a required capacity of ~8.82 kW, providing the starting point for all other calculations.

### Weighing between buying or renting
A client asks: 'Should I buy my solar system outright or should I use a PPA?' The agent uses `compare_financing_models` to show that while the PPA has zero upfront risk, purchasing offers the lowest net cost over 25 years.

### Understanding long-term savings
The user asks: 'What are my total projected savings if I install a 10kW system costing $20,000?' The agent runs `calculate_financial_returns` and outputs an estimated payback period of 6.5 years with over $32k in total savings.

### Showing the environmental benefit to my family
The user asks: 'How much pollution will this system prevent?' The agent runs `estimate_environmental_impact` and gives a concrete figure for avoided CO2 emissions, making the sustainability case tangible.

## Benefits

- Determines the exact system size you need. The `estimate_system_capacity` tool takes your usage data to give you a precise kW requirement, so you don't overbuy or under-plan.
- Provides clear financial planning. Use `calculate_financial_returns` to model total savings and know exactly when you hit break-even, eliminating guesswork.
- Compares financing options side-by-side. The `compare_financing_models` tool lets you weigh the risks of purchasing versus the low upfront cost of a PPA in one view.
- Measures your impact instantly. You can use `estimate_environmental_impact` to see your carbon offset potential, proving the project's value beyond just money.
- Saves time on feasibility studies. Instead of calling an engineer for basic sizing data, you get immediate estimates using the MCP.

## How It Works

The bottom line is that it converts raw energy numbers into actionable financial and sustainability plans for your home.

1. Input your home's total annual energy usage (kWh) and the average peak sun hours available at your location.
2. The MCP first uses this data to determine the minimum required solar system capacity, giving you a technical baseline.
3. Next, run financial models by providing costs and utility rates to calculate projected savings, payback periods, and environmental impact.

## Frequently Asked Questions

**How do I know if solar power is financially worth it for my home?**
The Solar Panel Calculator MCP calculates the full Return on Investment (ROI). By using the `calculate_financial_returns` tool, you get a precise payback period and total projected savings over 25 years so you know exactly when to break even.

**Can I compare buying solar panels vs. financing through a PPA?**
Yes, the MCP handles this comparison perfectly. The `compare_financing_models` tool lets you run Purchase, Lease, and PPA options simultaneously, showing which structure has the lowest net cost for your specific property.

**What do I need to input first to calculate system size?**
You must provide your home's total annual energy usage in kilowatt-hours (kWh) and the average number of peak sun hours at your address. The MCP uses these figures with `estimate_system_capacity` to give you a precise kW requirement.

**Does Solar Panel Calculator help me track my environmental impact?**
Absolutely. The `estimate_environmental_impact` tool quantifies your carbon offset potential, allowing you to measure the full sustainability value of going solar beyond just dollar savings.
