How Sunbox Benefits Tennessee Homeowners

Sunbox is an ideal choice for environmentally conscious homeowners looking for cost-effective green energy solutions. Here are a few of the benefits of investing in the Sunbox system for your home.

An All-in-One Solution

Sunbox contains everything you need to start using solar power right away. When you choose the Sunbox Plus, you’ll have peace of mind knowing you also have a backup power supply in the event of an emergency.

Cost Savings

When you start using a Sunbox system, you’ll gain energy independence that minimizes your reliance on the national electric grid. This independence will reduce your susceptibility to rising electricity costs, saving you money on your utility bills. Sunbox also has a strong return on investment, typically paying for itself after several years.

Environmental Sustainability

The Sunbox is a renewable energy solution that reduces toxic emissions. Electricity from the grid is produced by burning non-renewable fossil fuels, which creates greenhouse gases that damage the environment and people’s health. By switching to a solar energy system, you can help reduce greenhouse gases and contribute to a healthier environment.

Increased Property Value

Installing Sunbox updates your home’s exterior and increases its value. Buyers typically consider solar systems a major home upgrade, like a renovated kitchen or finished basement. They’ll pay more for a home that comes with a built-in, sustainable power supply that will save them money over time.

Low Maintenance

The Sunbox solar system needs little maintenance to stay in top condition. It’s built with durable properties to withstand the elements, requiring minimal repairs over its lifetime.

How Sunbox Works

Sunbox is a complete solar system that has everything you need to produce your own electricity. Each Sunbox system includes:

  • Solar panels
  • Optimizers
  • An inverter
  • Battery storage
  • Racking

The solar panels contain photovoltaic (PV) cells that capture sunlight to produce direct current (DC) electricity. The optimizers increase energy output from the PV cells for maximum performance, and the inverter changes DC electricity to alternating current (AC) electricity, which is compatible with most homes. The converted electricity feeds into your electrical panel to power your home.
