Solar Site Intelligence Report
Click any module from the right panel to add it to this report. Each module checks a different aspect of the solar system - from space and hardware to costs and energy savings.
Based on the monthly bill and tariff rate you entered, this calculates how much energy you use and what size solar system (in kWp) you need to cover it completely. You can also choose the solar panel wattage your company uses. The tool also recommends the right solar inverter size for your system.

System Sizing & Generation Profile
System sized to offset 100% of current consumption. All figures based on site-specific solar irradiance modeling.
Planning to add appliances like air conditioning, EV charging, water pumps, or induction cooktops later? It costs much more to upgrade a solar inverter after installation than to install a bigger one now. This module calculates the additional energy (kWh) needed and tells you the exact inverter size (kW) you should install today to avoid costly upgrades later. It also calculates how many extra solar panels you will need and whether additional roof space is required.

Future Load Expansion Analysis
Planning for future loads now avoids costly inverter replacements later.
Solar panels need space on your roof or ground. Fire safety rules say we must keep 30% open area for walkways and wind protection. This tool also lets you enter custom PV panel dimensions or uses the industry standard 2274×1134mm (2.58m²) panel size. If extra space is available, it will recommend a larger inverter for future solar expansion.

Site Location & Climate Analysis
Panel orientation optimized for maximum annual energy yield at this latitude.
This uses 5 years of real weather data (sunlight and temperature) from your location to estimate how much energy your solar system will produce each year. P50 is the average expected yield. P90 is the guaranteed minimum (90% chance of achieving this). Banks use P90 for loan approvals.

Energy Production & Bankability Assessment
P90 is the minimum production with 90% confidence — the bankable figure used for financial approvals.
Solar Metrix Pro is a comprehensive PV solar system design and engineering analysis platform built for solar installers, EPC contractors, and end-users. It performs solar site assessment, solar PV sizing, battery storage calculation, rooftop solar feasibility, and financial ROI analysis - all in one browser-based tool. Below is how each module works and who benefits from it.
Your data stays on your device. Solar Metrix Pro runs entirely in your browser. No data you enter - bills, client names, coordinates, or company details - is ever sent to any server.
Local Storage: Your inputs (bill amount, tariff rate, coordinates, installer details) are saved in your browser's local storage so you do not lose them when you refresh the page. This data never leaves your computer.
External APIs: When you use the Climate Yield or Location modules, weather data is fetched from open-meteo.com (free weather API) and location names from openstreetmap.org. Your coordinates are sent to these services only when you run those modules. No personal or company data is shared.
No Tracking: This tool does not use cookies, analytics, or any tracking scripts.
Report Data: When you save a report, the HTML file is downloaded to your computer. We have no access to these reports.
Third-Party Libraries: This tool uses Tailwind CSS, Chart.js, and Lucide icons loaded from CDNs. These services may have their own privacy policies.

Should you buy a battery or just use the grid? Enter your proposed battery capacity in Ampere-hours (Ah) as written on the battery spec label, along with the battery voltage. The tool converts Ah to kWh and compares net metering vs hybrid battery storage. If you do not know what battery capacity you need, use the Battery Backup Sizing and Battery LCOS modules first.

Grid vs. Battery Storage Optimization

Cheaper batteries (Tubular Lead-Acid) may seem like a good deal upfront, but they die faster (3 years) and waste 20% of energy as heat. Lithium batteries cost more upfront but last 10+ years and waste less. This tool shows the REAL 10-year cost including electricity price increases.

Battery Chemistry & 10-Year Cost Analysis (LCOS)
LCOS accounts for hardware replacements, heat waste losses, and 8% annual grid inflation over 10 years.
Calculate exactly what battery capacity (Ah and kWh) you need for your day and night loads. Enter your load in kWh and desired backup hours. The tool compares tall tubular lead-acid vs lithium LiFePO4 batteries showing their depth of discharge (DoD), round-trip efficiency (RTE), and daily energy waste. If you already know your battery requirements, use the Battery LCOS and Grid vs Battery modules for financial comparison.

Checks if the inverter and solar panels work well together. In cold weather, panel voltage can rise and damage the inverter. Too many panels on a small inverter causes energy loss (clipping). This tool checks if the hardware is a safe match.
