1. What is the Company Rating Formula?

The Company Rating Formula evaluates solar battery storage companies by comparing their storage capacity to price. This simple metric helps consumers identify the best value options in the market.

2. How Does the Calculator Work?

The calculator uses the following equation:

Where:

• Storage Capacity — Total energy storage in kilowatt-hours (kWh)
• Price — Total cost in dollars ($)

Explanation: Higher ratings indicate better value, meaning more storage capacity per dollar spent.

3. Importance of Battery Storage Ratings

Details: Comparing solar battery storage options helps consumers make informed decisions about their energy investments, balancing capacity needs with budget constraints.

4. Using the Calculator

Tips: Enter the total storage capacity in kWh and the total price in dollars. Both values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: What is a good rating value?
A: Higher values are better. Typical residential battery systems might range from 0.01 to 0.05 kWh/$.

Q2: Should I only consider the rating when choosing a battery?
A: No, also consider warranty, brand reputation, efficiency, and compatibility with your solar system.

Q3: Does this account for installation costs?
A: The price should include all installed costs for accurate comparison.

Q4: How does battery lifespan factor into this rating?
A: This simple rating doesn't account for lifespan. For long-term value, consider cycle life and warranty.

Q5: Are there other important battery specifications?
A: Yes, also consider depth of discharge, round-trip efficiency, and power output capabilities.
