Phase 1: Initialization

Beginner’s Guide & System Sizing

Most solar fears fade once you understand the math. Let's map your roof, size your system, and check your readiness.

1. Roof Intelligence

Before buying panels, you need to know if your "foundation" is ready. Here is the breakdown of positioning, shade, and climate factors.

Positioning South-facing is ideal. East/West works too (slightly less output).
Shade & Clouds Not fatal. Micro-inverters handle partial shade. Panels still work on cloudy days (~25% output).
Cold Climates Cold is actually good. Panels are more efficient in cool weather (as long as snow is cleared).
Structural Most standard roofs can handle the weight. A quick pro check confirms this.

How to Check Your Roof

  1. Look at angle & direction: South is best, but 30° East/West is viable.
  2. Note major shading: Trees or buildings casting shadows between 9am-3pm?
  3. Get a Pro Assessment: Most installers do this for free.
  4. Check Roof Age: Critical! If your roof is >15 years old, replace it before solar.

Roof not fit? Alternative Options

Ground-Mounted

Panels installed in your yard or open land. Great for rural properties.

Carports / Pergolas

Stylish structures that double as shade and power generators.

Community Solar

Join a shared solar farm and earn credits. No roof needed.

Solar Shingles

Integrated into roof tiles. Ideal for aesthetics or strict HOAs.

2. Understanding Your Energy Needs

Knowing your numbers busts myths and drives fear away. Solar systems are sized based on how much electricity you actually consume, not just square footage.

Where to find your usage

Grab your utility bill. Look for a section labeled "kWh Usage" or "Energy Consumption". A graph showing 12 months is the gold standard.

What is 1 kWh?
Running a 1000-watt appliance for 1 hour.
(e.g., Running a 100W lightbulb for 10 hours = 1 kWh)

Your Usage Patterns

Most households peak at specific times. Knowing this helps later with battery planning.

  • Summer: High usage (AC cooling).
  • Winter: High usage (Heating systems).
  • Evenings: Lighting + Entertainment.

Calculate Your Needs

Now that you have your bill, estimate the system size you need.

Solar System Size & Cost Calculator

Estimate the system size you need and the potential costs involved.

kWh
Found on your utility bill. Average US home is ~900 kWh.
Cloudy (2h) Sunny (8h)
Most of US is 4-5 hours. Not sure?
National Avg is ~$3.00/watt before incentives.

3. Financial Mapping

Solar is an investment. The "Funky Formula" explains why savings grow as utility rates rise.

Avoided Cost The Biggest Win
Incentives & Rebates The Upfront Boost
Home Value Increase The Long-Term Asset

1. Investment Details
$
Gross cost before incentives.
$
e.g. Federal Tax Credit (30%).
2. Savings & Expenses

$
Optional (cleaning, inspections).
Total Savings = Σ [Annual Savings × (1 + Inflation)^Years]

Translation: A $1500 saving today becomes $1545 next year just by avoiding utility rate hikes.

Check your bill (e.g., $0.18).
Step 2: Apply Inflation

Utility rates historically rise ~2.85% per year.

4. Warranties & Permits

Never sign a contract without verifying these protections.

Solar Protection Checklist

Don't sign until you have verified these specific warranties and permits.

✅ The 3 Must-Have Warranties

Ensure your contract explicitly covers these items.

Look for: Panels (25 yrs), Inverters (10-25 yrs), Batteries (10-15 yrs).
Look for: 10 years minimum. Covers roof leaks, wiring, and mounting failure.
Look for: Annual kWh guarantee. Max degradation 0.5%/year.

📄 Required Legal Permits

Your installer handles these, but you must verify they exist.

Confirms roof load safety. Never start work without this.
Ensures NEC compliance for wiring and breakers.
Permission to Operate. You cannot turn the system on without this.
Check community rules. Most states protect solar rights, but approval is often still required.
