The design will also specify whether it’s a grid-tied system, which remains connected to the utility, or a completely independent off-grid solar solution. The choice impacts the installation steps, as detailed in Grid-Tied vs Off-Grid: How Installation Steps Differ. Finally, you receive a detailed proposal outlining the system’s cost, projected energy production, and estimated savings. This proposal marks one of the first key moments in your project timeline. For more on this, see 9 Milestones From Quote to PTO in a Solar Install.
A crucial part of the design is deciding whether to include an energy storage system (ESS). Integrating a high-performance LiFePO4 (Lithium Iron Phosphate) battery allows you to store excess solar energy for use at night or during power outages. Our home energy storage systems combine lithium batteries and a hybrid inverter for a streamlined and reliable solution, giving you greater control over your power. You can learn more about Integrating LiFePO4 Storage During Solar Commissioning.
If your system includes monitoring (as most systems do), it will allow you to check that it’s generating as expected.
The amount of electricity generated each day varies according to the time of year and the weather, but if it is lower than usual on sunny days, there may be something wrong.
Some monitoring systems will tell you automatically if the generation is less than it should be, for example, if there is a problem with excessive shading.
Your inverter may show a fault code if there is an issue.
If you have a battery, the monitoring system will show you if it is charging and discharging regularly.
