Everything you need to know about DIY solar design and our services

General Solar Questions

Most homeowners save 40-60% compared to professional installation, typically $12,000-$18,000 on an average residential system. Here's the breakdown:


Professional Installation: $2.50-$3.50 per watt ($20,000-$28,000 for 8kW)


DIY with Our Services: $1.30-$2.20 per watt ($10,400-$17,600 for 8kW)


Savings: $9,600-$10,400+ (40-60%)


The savings come from eliminating installation labor markup (typically $1.00-$1.50/watt) while still getting professional design and engineering.


Additional benefit: Better ROI. Professional systems typically pay back in 8-10 years, while DIY systems pay back in 4-6 years.

If you're reasonably handy and comfortable with electrical work (or willing to hire an electrician for final connections), yes! Most DIY solar installers successfully complete their projects by:


What makes it feasible:

  • Modern plug-and-play equipment (especially microinverters)
  • Comprehensive installation guides from manufacturers
  • Our detailed design documents and support
  • YouTube tutorials and DIY solar communities
  • Licensed electrician for final electrical work (recommended)

  • Skills needed:

  • Comfortable working on roof (or hire roofer for mounting)
  • Basic carpentry/construction
  • Ability to follow detailed instructions
  • Basic electrical knowledge (or hire electrician)

  • What we provide:

  • Professional system design
  • Detailed installation drawings
  • Equipment selection and specifications
  • Technical support during installation
  • Code-compliant engineering

  • Important: You don't have to do everything yourself. Many DIY'ers hire contractors for specific tasks (roof mounting, electrical connections) while doing the rest themselves - still saving 30-40%.

    Timeline breakdown:


  • Design phase (us): 5-7 business days
  • Permitting: 2-6 weeks (varies by jurisdiction)
  • Equipment ordering: 1-3 weeks
  • Installation (you): 1-5 days for typical residential system
  • Inspection & interconnection: 1-3 weeks

  • Total: 6-12 weeks from design request to system activation


    The actual installation work is typically 2-4 days for a residential system (spread over weekends). Commercial or complex systems may take longer.

    Great question! Here's the comparison:

    Yes! Solar works in all 50 states - even Alaska. Here's why:


  • Solar panels produce electricity from light, not heat
  • Germany (cloudier than most US states) is a global solar leader
  • Cold climates can actually boost panel efficiency
  • Snow reflects light, increasing production

  • We've designed systems in:

  • Sunny states: California, Arizona, Texas, Florida
  • Cloudy states: Washington, Oregon, Pennsylvania
  • Cold states: Alaska, Montana, Minnesota, Maine
  • Everything in between

  • What matters more than climate:

    1. Electricity rates (higher rates = better ROI)

    2. Available incentives

    3. Roof orientation and shading

    4. Available roof space

    When electrician is recommended:

  • No electrical experience
  • Uncomfortable with electrical work
  • Service panel upgrade required
  • Unfamiliar with NEC code
  • Complex string inverter wiring
  • Battery integration

  • What electrician typically does:

  • Final AC interconnection (inverter to panel)

  • Meter installation (if allowed)
  • Final inspection sign-off

  • What you can typically do yourself:

  • Mounting panels
  • DC wiring (panels to inverter)
  • Conduit installation
  • Microinverter wiring (simpler than string)
  • Basic connections

  • Electrician cost:

  • Simple interconnection: $500-$1,000
  • Panel upgrade + interconnection: $1,500-$3,000
  • Complex systems: $2,000-$4,000

  • Still saves money:

  • Professional install labor: $8,000-$15,000
  • Electrician: $500-$3,000
  • Net savings: $5,000-$12,000

  • Local requirements:

  • Some jurisdictions require licensed electrician for final connection
  • We advise on your area's specific requirements
  • Many allow homeowner electrical work on own property

  • Our recommendation:

  • Do the roof work yourself (or hire roofer)
  • Have electrician do final electrical (safer, code-compliant)
  • Best of both worlds: maximum savings, professional electrical
  • Most are common tools, some are solar-specific:

    Depends on your goals and situation:


    Good reasons to add batteries:

  • ✓ Frequent power outages
  • ✓ Essential backup needed (medical equipment, refrigeration)
  • ✓ Hurricane/storm-prone area
  • ✓ Grid unreliable
  • ✓ Time-of-use (TOU) rates with expensive peak hours
  • ✓ Want energy independence
  • ✓ Future grid resilience concerns

  • Reasons to skip batteries (for now):

  • ✗ Reliable grid
  • ✗ Net metering available (grid = free battery)
  • ✗ Budget constrained
  • ✗ Flat/tiered rates (no TOU pricing)
  • ✗ No critical backup needs

  • Financial consideration:

  • Batteries add $10,000-$20,000
  • ROI depends on utility rates and outage frequency
  • Backup value vs. financial payback

  • Our recommendation:

  • Design system "battery-ready"
  • Add batteries now or later
  • Many inverters support battery addition
  • Future battery costs expected to decrease

  • We design both:

  • Grid-tied only (no battery)
  • Grid-tied with battery backup
  • Show cost comparison
  • Depends on what you want to power and for how long:


    Essential Loads Only (8-12 hours):

  • Refrigerator: 150W average
  • Internet/router: 50W
  • LED lights: 100W
  • Phone charging: 50W
  • Total: ~350W × 10 hours = 3.5 kWh
  • Battery needed: 5-7 kWh (accounting for efficiency)
  • Cost: $6,000-$10,000

  • Partial Home Backup (12-24 hours):

  • Essential loads: 350W
