We’ve answered the most common questions to help you understand solar energy, installation, costs, and maintenance.
The cost depends on your energy needs and system size. A typical residential system starts from a few hundred thousand rupees, while commercial and industrial systems vary based on load requirements. We provide a detailed, transparent quote after a free site assessment. No hidden costs, No surprises.
Most residential installations are completed within 1–3 days. Commercial and industrial projects vary depending on system size and site conditions. Our team works efficiently to minimise disruption to your home or business.
Yes. Modern high-efficiency solar panels continue to generate electricity even in low-light and overcast conditions — just at a reduced rate. Battery storage can also be added to ensure you have power available at all times.
ALTREX systems are built for the long term. Our panels carry a 25-year performance warranty, with most systems continuing to generate clean energy well beyond that with minimal maintenance.
Absolutely. We manage the entire process from NEA metering setup and grid connection approvals to all necessary documentation — so you don't have to worry about the paperwork.
