Thinking about solar panels system for your place? It’s a big step. Saves money on bills, helps the planet. But not every house fits the bill. That’s where the Sun Number Score comes in. It’s like a report card for your home’s solar potential. Scores run from 0 to 100. Higher means better. In this post, we’ll break down if your house suits solar panels. We’ll look at factors that affect your home’s sun number score. You’ll see what counts, why it matters, and how to check. Let’s dive in.
Understanding the Sun Number Score
What exactly is this score? Sun Number, a company pushing solar awareness, came up with it. They rate buildings on solar fit. Enter your address on their site or Zillow—it pops up for millions of homes. The score shows how much solar energy your spot can grab.
It’s simple. 0 is bad, 100 is top-notch. Most homes land somewhere in between. But why care? It tells you if panels make sense. Low score? Might still work, but output drops. High score? Big savings ahead.
House sketches with numbers show potential. Imagine one at 70—good. Another at 90—great. It guides decisions.
Why This Score Matters to Homeowners
Scores help in big ways. For folks buying homes, it’s key info. Zillow lists it for 84 million places. Buyers want high scores. Means lower energy costs, higher home value.
Selling or renting? Solar boosts appeal. Studies say homes with panels sell faster, fetch more cash. One report pegs added value at thousands.
Even if staying put, the score spots savings. Cut bills by 50-70% in sunny spots. Plus, tax breaks like the federal credit sweeten deals.
70% score example. That’s solid. Means panels pay off quick.
What Counts as a Strong Sun Number Score?
The scale: 0-100. Aim for 70 or up. That’s prime for solar. At 70, expect good energy output, solid returns.
100? Rare perfection. Ideal roof, tons of sun, low install costs.
Below 70? Not hopeless. Score 60 might work if you tweak things. But expect less power, longer payback.
Real talk. Most U.S. homes score 60-80. Sunny states like California or Arizona hit higher. Cloudy ones? Lower.

Main Factors That Affect Your Home’s Sun Number Score
Several things shape the score. Roof setup, local weather, power rates, install prices. Let’s unpack each.
Roof Suitability and Design
Your roof is the star. Size, direction, slope—all count.
Bigger roof? More panels, higher score. South-facing roofs catch max sun. They generate plenty, even extra for batteries or grid sell-back.
East or west? Still okay, but less efficient. North? Tougher, score drops.
Slope matters. 30 degrees is best. Steeper or flatter? Brackets adjust. But extreme angles hurt.
Table on roof impacts:
| Roof Feature | Ideal Setup | Score Impact |
| Direction | South-facing | High boost |
| Size | Large area | Increases score |
| Slope | 30 degrees | Optimal |
| Material | Asphalt or metal | No big change, but check weight |
Bullet points on common issues:
- Shading from chimneys or vents? Cuts score.
- Old roof? Fix first, panels last 25 years.
- Space for 10-20 panels? That’s typical for average home.
Score here often 40-60 points. Key to overall.
Local Climate and Sun Exposure
Where you live plays huge. Sunny days lift scores.
Colorado gets 300 sunny days yearly. Perfect. Seattle? More clouds, lower score.
Sun Number uses NREL data for irradiance. Measures sun strength.
Surroundings count. Trees, buildings block sun? Score falls. Trim branches or pick ground mount.
Hot spots? Panels like mild temps. Extreme heat cuts efficiency slightly.
Bullet points on climate tips:
- Check annual sun hours. 1,500+ is good.
- Overcast areas? Bigger system compensates.
- Pollution or dust? Clean panels regular.
This factor adds 20-30 points usually.
Electricity Rates in Your Area
Power costs affect the score big. High rates? Higher score. Solar saves more where bills sting.
Think Hawaii—rates double mainland. Score jumps.
Low rates? Like in Washington state. Less incentive, score dips.
Sun Number factors average local rates. Shows payback time.
Example: $0.20/kWh? Fast returns. $0.10? Slower.
Cost of Solar Installation Locally
Flip side of rates. Low install costs boost score. High ones drag it.
Prices vary. California: competitive, lower per watt. Rural spots: higher due to travel.
Includes permits, labor. Federal tax credit (30% till 2032) helps everywhere.
Table comparing costs:
| Region | Avg Cost per Watt | Score Effect |
| Sunny states | $2.50 | Positive |
| High labor areas | $3.50 | Negative |
Shop quotes. Multiple bids cut costs.
Other Things to Think About
Beyond basics, extras influence.
Age of home. Newer wiring handles solar easy. Old? Upgrades needed.
HOA rules. Some restrict panels. Check first.
Incentives. State rebates add value, indirectly lift effective score.
Batteries? Pair with panels for off-grid feel. HITEK ENERGY offers combos.
Steps to Check and Improve Your Score
Curious? Search your address on Sun Number site.
Low? Ways to fix:
- Clear shade.
- Chooseefficient panels like N-Type TOPCon.
- Get pro assessment.
Tools estimate. But experts confirm.
