Value Formula:
| From: | To: |
The Solar PV Value Calculator determines the financial value of a solar photovoltaic system by calculating the difference between energy savings and system costs. This helps homeowners and businesses evaluate the economic viability of solar investments.
The calculator uses a simple value formula:
Where:
Explanation: The formula calculates the net value of a solar PV system by subtracting the total installation and maintenance costs from the total energy savings generated over a specific period.
Details: Accurate value calculation is essential for making informed decisions about solar investments, assessing return on investment, and comparing different solar system options.
Tips: Enter energy savings in dollars, system cost in dollars. Both values must be non-negative numbers. The result shows the net value of your solar PV system.
Q1: What factors contribute to energy savings?
A: Energy savings include reduced electricity bills, government incentives, tax credits, and potential income from selling excess energy back to the grid.
Q2: What costs should be included in system cost?
A: System cost includes equipment purchase, installation labor, permits, maintenance, and any financing costs associated with the solar PV system.
Q3: How accurate is this value calculation?
A: This provides a basic net value calculation. For more comprehensive analysis, consider factors like system lifespan, degradation rates, and future energy price changes.
Q4: What does a negative value indicate?
A: A negative value suggests that the system costs exceed the energy savings, indicating the investment may not be financially beneficial based on the input parameters.
Q5: Should I consider other financial metrics?
A: Yes, for complete financial analysis, also consider payback period, return on investment (ROI), and internal rate of return (IRR) alongside the net value.
