This comprehensive report provides a deep dive into the financial viability of solar energy systems across key global markets in 2024. Designed for homeowners, businesses, investors, and policymakers, it combines technical, economic, and policy insights to answer the critical.
The Renewable Energy Test Center has released its 2025 PV Module Index, assessing solar module reliability, quality, and performance across industry benchmarks. The report highlights manufacturers that meet high standards in long-term durability and energy yield.
This means the panel can produce 100 watts of power under optimal conditions. Since optimal conditions are impossible to achieve at all times, I usually recommend to estimate a 70-80% efficiency when calculating how much solar you need for a specific application.
NREL analyzes the total costs associated with installing photovoltaic (PV) systems for residential rooftop, commercial rooftop, and utility-scale ground-mount systems. This work has grown to include cost models for solar-plus.
This study presents the design, simulation and performance analysis of a 650 kW on-grid solar electricity generation system for a rural community in Rivers State, Nigeria, using the photovoltaic system (PVsyst) software. The model consists of 2500 PV modules each with a rating.
For the 29th consecutive year, the IEA-PVPS Trends report is now available. This document provides the most comprehensive global overview of the development of the Photovoltaics sector, covering policies, drivers, technologies, statistics and industry analysis.
In 2025, researchers found potential solutions to deficits in transparent, thin-film, and perovskite solar panels. They also discovered ways to tackle – and utilise – the effects of heat on solar installations. We've chosen our nine favourite advances to highlight and explain.
Solar panel manufacturing can release various pollutants, including heavy metals like lead and cadmium, as well as volatile organic compounds (VOCs) and wastewater contaminated with chemicals used in the production process.
Solar panel & photovoltaic module testing is applicable across various sectors including renewable energy projects, residential solar installations, commercial building integrations, and grid-tied systems.
