Installed Solar vs Safe Hosting Capacity — 12 Months
Click to expand
Safe hosting capacity varies seasonally — lower during wet season (reduced load means less room for solar), higher during dry/peak demand months when the grid can absorb more.
Grid Hosting Analysis
Based on feeder-level voltage rise and stability analysis, this grid can safely host up to 520 kWp of solar. You currently have 340 kWp installed, leaving 180 kWp of room.

Recommendations
☀️
Expand Solar Capacity by 180 kWp
You have 180 kWp of room before hitting the grid's safe hosting limit (520 kWp). Adding 180 kWp across 3 feeders would maximize your solar capacity and save an estimated $3,794/month in diesel costs, with payback in under a year.
$3,794/month diesel savings~635 kg CO₂/month avoided
🔋
Consider Battery Storage for Higher Solar Share
To go beyond the current 520 kWp hosting limit, battery storage would be needed to absorb excess solar during low-load periods and provide frequency support. A 100 kWh battery could safely unlock an additional 80-100 kWp beyond the current limit.
