Solar Panel Installation (G03)

Solar panels reduce electricity costs and environmental impact – exceptionally viable in Utah with 300+ sunny days annually and strong net metering policies.

This BidScope covers system types (grid-tied with net metering, battery backup, off-grid), panel technology (monocrystalline, polycrystalline, thin-film efficiency differences), sizing and design (calculate energy needs, roof assessment, optimal placement), and installation (permitting, electrical integration, monitoring systems).

Learn system types: grid-tied (most common, sell excess to utility, net metering credit, no batteries), battery backup (grid-tied plus battery storage, power during outages, higher cost), off-grid (complete independence, large battery bank, generator backup, remote properties).

Understand panel technology: monocrystalline (18-22% efficiency, black uniform appearance, premium cost, best for limited space), polycrystalline (15-17% efficiency, blue speckled, economical, slightly lower performance), thin-film (10-13% efficiency, flexible applications, lowest cost per watt).

Master sizing calculations: annual consumption (review utility bills kWh per year, typical Utah home 10,000-15,000 kWh), system size (divide consumption by 1,400 sun hours Utah average, 7-10 kW typical residential), roof space (300-400 square feet per kW, south-facing optimal).

Navigate Utah incentives: federal tax credit (30% through 2032, then decreases, applies to equipment and installation), utility rebates (Rocky Mountain Power and others, varies by program), property tax exemption (solar equipment exempt from property tax assessment, significant savings), increased home value (average $15,000-20,000 value add).

Learn installation requirements: roof condition (must last 25+ years, replace before solar if needed), structural capacity (40-50 pounds per panel, engineering may be required), electrical service (may need panel upgrade for additional circuits), permits (building and electrical, utility interconnection agreement).

Understand net metering: excess production (credits at retail rate, banked monthly), true-up (annual reconciliation, paid for excess at wholesale or lost), time-of-use (future rates may pay more for afternoon production), policy changes (Utah considering changes, current policy favorable).

Know mounting systems: roof-mount (most common, racking systems, asphalt shingle, tile, metal roof adapters), ground-mount (easier maintenance, optimal angle possible, requires land), carport or pergola (dual purpose, shade and solar), flat roof (ballasted or penetrating mounts).

Navigate inverter types: string inverters (one inverter for array, economical, shading affects all), microinverters (one per panel, optimize individually, higher cost, better partial shade), power optimizers (hybrid approach, panel-level optimization, string inverter).

Learn battery storage: lithium-ion (Tesla Powerwall, LG Chem, 10-15 kWh typical, $8,000-15,000 installed), backup capacity (whole house versus critical loads only, size to needs), solar charging (battery charges from solar, exports to grid when full), time-of-use arbitrage (charge when cheap, discharge when expensive).

Understand Utah-specific factors: high altitude (slightly better efficiency, cooler temps), snow (panels shed snow quickly, occasional cleaning), hail (tempered glass resists, insurance coverage verify), monsoon winds (proper mounting critical).

Navigate maintenance: cleaning (rain usually sufficient, occasional wash if dusty, avoid abrasives), monitoring (app tracks production, alerts to issues), inverter replacement (10-15 year lifespan, budget for future), panel degradation (0.5% annually, 25-year warranty 85% production).

Calculate costs and payback: typical 7 kW system $15,000-25,000 before incentives, federal tax credit reduces 30%, net cost $10,500-17,500, annual savings $1,000-1,500, payback 7-12 years, 25+ year lifespan.

This tool ensures solar systems are properly sized, permitted, and installed for maximum Utah sunshine benefit.
