Who is Will Prowse?
Will Prowse is a solar energy enthusiast and educator who has gained a significant following through his YouTube channel and website, DIY Solar Power with Will Prowse. His content focuses on making solar power accessible to everyone, from beginners to seasoned DIYers, with a hands-on approach emphasizing practical applications and real-world solutions.
Core Components of Solar Power Systems
Solar Panels
Will typically recommends high-efficiency monocrystalline panels from trusted brands such as:
- Renogy
- Rich Solar
- Newpowa
Charge Controllers
Prowse advocates for MPPT (Maximum Power Point Tracking) charge controllers, recommending:
- Victron SmartSolar
- EPEver Tracer
- Renogy Rover
Batteries
"LiFePO4 batteries may cost more upfront, but their longer lifespan and superior performance make them the most cost-effective choice in the long run."
Inverter
Converts stored DC power from the battery into AC power for household appliances.
System Sizing Guidelines
Small Systems (100-400W)
Perfect for:
- Van life setups
- Small camping systems
- Emergency backup power
Medium Systems (400-1500W)
Ideal for:
- RV installations
- Tiny homes
- Workshop power
Large Systems (1500W+)
Suitable for:
- Full home backup
- Off-grid living
- Small businesses
Installation Best Practices
- Wire Sizing
Wire Size = (Current × Length × 2) ÷ (Voltage × Acceptable Voltage Drop)
- Fusing Guidelines
- Always fuse batteries within 7 inches
- Size fuses at 1.25× the expected current
- Use proper marine-grade fuse holders
Monitoring and Maintenance
| Timeframe | Maintenance Task |
|---|---|
| Weekly | Check battery voltage levels |
| Monthly | Clean solar panels |
| Quarterly | Inspect all connections |
| Annually | Full system audit |
Benefits of Solar Power
- Renewable and Sustainable: Solar power is non-depletable, unlike fossil fuels
- Zero Emissions: Generates electricity without greenhouse gases
- Low Maintenance: Solar panels require minimal maintenance and last 30+ years
- Energy Independence: Generate your own electricity and reduce grid reliance
- Cost Savings: DIY systems offer significant savings on installation and equipment
- Customization: Greater flexibility to meet specific energy needs
