Technical Detail
Here are some answers to common questions about installing a battery-ready solar power system and powering an EV using solar energy.
How much is a battery-ready solar power system?
The cost of a solar power system depends on your home's energy usage and the system's setup.Β In New Zealand, a battery-ready solar power system typically ranges from $9,000 to $18,000, depending on your power needs.
Will EV charging significantly reduce the amount of solar power available for home use?
EV charging can be scheduled during peak solar production hours, which coincide with periods when home energy needs are lower.Β In this way, it allows the vehicle to use surplus power that the home doesn't consume.
What are the benefits of installing a battery-ready solar power system?
A battery ready system is a lower cost option the enables you to assess the benefits of a solar-only system before investing in batteries.Β By installing a battery ready system you can add a battery without upgrading the inverter.
