Everything You Need to Know Before Going Solar

We believe the best solar customer is an informed one. Read through these sections before speaking to our team.

Common myths about solar — and what the reality actually is.

Myth: Solar doesn't work on cloudy days

Reality: Solar panels generate electricity from daylight, not just direct sunlight. On cloudy days, output is reduced by 10–30%, but panels continue to generate power. Andhra Pradesh has excellent solar radiation levels year-round, making it one of India's best states for solar energy.

Myth: Solar systems require constant maintenance

Reality: Solar systems have no moving parts and require very little maintenance. Occasional panel cleaning (2–4 times per year) and an annual electrical inspection are sufficient. Good quality panels can operate for 25+ years with minimal intervention.

Myth: Solar is too expensive to be worthwhile

Reality: Solar panel costs have fallen over 80% in the last decade. Most commercial installations in AP pay back in 4–6 years and then generate essentially free electricity for the remaining 20+ years of the panel life. The question is no longer whether solar is affordable — it is whether you can afford not to switch.

Myth: Solar damages the roof structure

Reality: When installed correctly by trained professionals, solar panels do not damage roofs. Proper mounting systems distribute weight evenly and use weatherproof fasteners. In many cases, solar panels protect the roof surface by shielding it from sun and rain exposure.

Myth: Grid power is more reliable than solar

Reality: Grid-tied solar systems still use the grid as backup — so you don't lose reliability. You reduce your dependence on (and payments to) the grid during the day, while retaining the grid connection for evening and night. Hybrid and battery systems can provide further independence.

Why solar makes strategic and financial sense for commercial and residential properties.

💰

Reduced Electricity Costs

Solar directly offsets your grid consumption during peak production hours — typically 9am to 4pm — which is exactly when commercial electricity is most expensive.

📈

Long-Term Price Stability

Grid tariffs increase 4–6% per year on average. Solar fixes your generation cost at zero for 25 years — turning a recurring liability into a long-term asset.

🌱

Environmental Responsibility

Solar reduces your organisation's carbon footprint — increasingly important for institutional credentials, CSR reporting, and customer perception.

⚡

Net Metering Credits

Surplus power generated during low-consumption periods is fed back to the grid and credited on your electricity bill — further reducing costs.

🏛️

Government Incentives

Accelerated depreciation, subsidies (residential), and tax benefits make solar an even stronger financial case for businesses and institutions.

🔒

Energy Independence

Reducing grid dependency protects businesses from load-shedding disruptions and reduces exposure to grid instability during peak demand periods.

Why Andhra Pradesh is one of the best locations in India for solar energy.

            AP Solar Potential at a Glance
            Andhra Pradesh receives an average of 4.5–6 peak sun hours per day — well above the national average. The state is consistently ranked among India's top 5 states for solar energy potential.
          

☀️

4.5–6 Peak Sun Hours/DayAndhra Pradesh receives consistently high solar irradiance across most districts throughout the year.

📅

300+ Sunny Days Per YearThe state's climate ensures a high proportion of clear and partly-cloudy days ideal for solar generation.

📊

5.5 kWh/m²/day Average RadiationThe Global Horizontal Irradiance (GHI) average across AP makes it economically viable for all rooftop types.

Solar Radiation by Region (AP)

Visakhapatnam ~5.2 kWh/m²/day

Vijayawada / Guntur ~5.4 kWh/m²/day

Tirupati ~5.3 kWh/m²/day

Kurnool ~5.8 kWh/m²/day

Anantapur ~5.9 kWh/m²/day

How Surya Power Tree ensures safe, standards-compliant solar installations.

🏗️

Structural Assessment

Every installation begins with a structural load assessment to ensure the roof can safely support the panel weight and mounting system.

⚡

Electrical Safety

All electrical work follows IS standards and CEIG guidelines. We use proper DC isolators, earthing systems, and surge protection devices on every installation.

🛤️

Rooftop Walkways

For large commercial and industrial installations, we install GRP (Fiberglass) anti-slip walkways with safety railings for safe access during maintenance.

🔌

Anti-Islanding Protection

Grid-connected systems include anti-islanding protection to prevent feedback to the grid during outages — protecting utility workers and the system.

🌡️

Thermal Management

Panel mounting maintains adequate air gap beneath panels for heat dissipation — preventing efficiency loss and protecting the roof membrane.

📋

Commissioning Inspection

Every installation is tested and inspected before handover — verifying all connections, output, and safety systems meet specification.
