A solar and battery system is a long-term investment that should save you money for many years. Choosing the right installer and the right equipment is just as important as choosing the right price. Here are the five most common mistakes we see and how to avoid them
1. Choosing the Cheapest Quote Instead of the Best Value
A low price can be tempting, but it often comes at a cost. Some installers reduce costs by using lower-quality equipment, cutting corners on installation, or offering little support once the system is commissioned.
What to look for:
- High-quality panels, inverters and batteries
- Experienced, qualified installers
- Clear warranties on both products and workmanship
- A detailed quotation explaining exactly what’s included
Remember: A quality installation will usually provide better performance, greater reliability and lower maintenance costs over its lifetime.
2. Buying a Battery That’s Too Small
Many homeowners are sold the smallest battery available because it keeps the quote looking attractive. Unfortunately, a battery that’s too small may not store enough energy to make a meaningful difference to your electricity bills.
A properly sized battery should be based on:
- Your daily electricity usage
- Whether you’re home during the day
- Whether you have an EV or heat pump
- Your future energy needs
A correctly designed system will often deliver a much better return on investment.
3. Not Planning for the Future
Your energy requirements may change over the next 10–20 years.
Consider whether you may later add:
- An electric vehicle charger
- Air conditioning
- A heat pump
- Additional battery storage
- More solar panels
Installing equipment that can be expanded later can save significant money compared with replacing components in the future.
4. Ignoring Monitoring and Smart Energy Management
Modern solar systems are far more than just panels on a roof.
The best systems allow you to:
- Monitor production and usage from your phone
- Charge batteries during cheaper electricity tariffs
- Automatically maximise self-consumption
- Track savings in real time
- Identify faults quickly
Without good monitoring, it’s difficult to know whether your system is performing at its best.
5. Choosing an Installer Who Doesn’t Properly Assess Your Property
Every home is different.
The right installer should consider:
- Roof orientation and pitch
- Shading from trees, chimneys or neighbouring buildings
- Your annual electricity usage
- Consumer unit capacity
- Cable routes
- Future expansion
- DNO requirements where applicable
A properly designed system almost always performs better than a standard “one-size-fits-all” package.
