Ashta, Maharashtra, India, located at 16.9596°N, 74.4174°E, presents a favorable environment for solar energy generation throughout the year. This tropical location benefits from consistent sunlight, with seasons characterized more by wet and dry periods rather than significant temperature fluctuations.

Seasonal Solar Performance

The solar energy output in Ashta varies across the meteorological seasons, with spring being the most productive period. During spring, solar panels can generate an impressive 6.73 kWh per day for each kilowatt of installed capacity. Winter follows as the second most productive season, yielding 5.36 kWh/day/kW. Autumn and summer produce slightly less, at 4.86 kWh/day/kW and 4.61 kWh/day/kW, respectively.

Optimal Panel Positioning

For fixed solar panel installations in Ashta, Maharashtra, the ideal tilt angle to maximize year-round energy production is 17 degrees facing South. This angle has been calculated considering the location's latitude, daily solar elevation angles, and weighted by NASA's solar irradiance data to account for Earth's elliptical orbit.

Environmental Considerations

While Ashta's climate is generally conducive to solar energy production, there are a few environmental factors to consider: 1. Monsoon season: The region experiences heavy rainfall during the monsoon months, typically from June to September. This can lead to reduced sunlight and potential panel soiling. 2. Dust accumulation: The dry seasons can result in dust buildup on solar panels, potentially reducing their efficiency. To mitigate these issues, consider implementing the following preventative measures: - Install a robust cleaning system or schedule regular manual cleaning to combat dust accumulation and monsoon-related soiling. - Use high-quality, weather-resistant solar panels designed to withstand heavy rainfall and humidity. - Implement a slight increase in panel tilt during the monsoon season to facilitate natural cleaning by rainwater. Overall, Ashta's location offers excellent potential for solar energy generation, with only minor challenges that can be effectively managed through proper installation and maintenance practices.

Solar output per kW of installed solar PV by season in Ashta

Seasonal solar PV output for Latitude: 16.9596, Longitude: 74.4174 (Ashta, India), based on our analysis of 8760 hourly intervals of solar and meteorological data (one whole year) retrieved for that set of coordinates/location from NASA POWER (The Prediction of Worldwide Energy Resources) API:

 

Ideally tilt fixed solar panels 17° South in Ashta, India

To maximize your solar PV system's energy output in Ashta, India (Lat/Long 16.9596, 74.4174) throughout the year, you should tilt your panels at an angle of 17° South for fixed panel installations.

As the Earth revolves around the Sun each year, the maximum angle of elevation of the Sun varies by +/- 23.45 degrees from its equinox elevation angle for a particular latitude. Finding the exact optimal angle to maximise solar PV production throughout the year can be challenging, but with careful consideration of historical solar energy and meteorological data for a certain location, it can be done precisely.

We use our own calculation, which incorporates NASA solar and meteorological data for the exact Lat/Long coordinates, to determine the ideal tilt angle of a solar panel that will yield maximum annual solar output. We calculate the optimal angle for each day of the year, taking into account its contribution to the yearly total PV potential at that specific location.

Seasonally adjusted solar panel tilt angles for Ashta, India

If you can adjust the tilt angle of your solar PV panels, please refer to the seasonal tilt angles below for optimal solar energy production in Ashta, India. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 17° South tilt angle throughout the year.

Overall Best Summer Angle	Overall Best Autumn Angle	Overall Best Winter Angle	Overall Best Spring Angle
1° South in Summer	23° South in Autumn	32° South in Winter	11° South in Spring

Our recommendations take into account more than just latitude and Earth's position in its elliptical orbit around the Sun. We also incorporate historical solar and meteorological data from NASA's Prediction of Worldwide Energy Resources (POWER) API to assign a weight to each ideal angle for each day based on its historical contribution to overall solar PV potential during a specific season.

This approach allows us to provide much more accurate recommendations than relying solely on latitude, as it considers unique weather conditions in different locations sharing the same latitude worldwide.

Calculate solar panel row spacing in Ashta, India

We've added a feature to calculate minimum solar panel row spacing by location. Enter your panel size and orientation below to get the minimum spacing in Ashta, India.

Our calculation method

1. Solar Position:
   We determine the Sun's position on the Winter solstice using the location's latitude and solar declination.
2. Shadow Projection:
   We calculate the shadow length cast by panels using trigonometry, considering panel tilt and the Sun's elevation angle.
3. Minimum Spacing:
   We add the shadow length to the horizontal space occupied by tilted panels.

This approach ensures maximum space efficiency while avoiding shading during critical times, as the Winter solstice represents the worst-case scenario for shadow length.

Topography for solar PV around Ashta, India

The topography around Ashta, India, located at latitude 16.9596 and longitude 74.4174, is characterized by a mix of flat plains and gently rolling terrain. This region, situated in the southern part of Maharashtra state, is part of the Deccan Plateau, which covers much of central and southern India. The landscape is predominantly rural, with agricultural fields dominating the scenery. The area surrounding Ashta features a network of small rivers and streams that flow through the countryside, creating shallow valleys and occasional low hills. These water bodies contribute to the region's agricultural productivity, as well as its slightly undulating topography. The elevation in this area generally ranges from about 550 to 650 meters above sea level, with minimal dramatic changes in altitude.

Suitability for Large-Scale Solar PV

When considering areas nearby that would be most suited for large-scale solar photovoltaic (PV) installations, several factors come into play. The flat plains surrounding Ashta offer excellent potential for solar energy development. These areas provide ample space for expansive solar arrays without the need for significant land modification or the challenges associated with hilly terrain. The regions to the east and southeast of Ashta are particularly promising for solar PV projects. These areas tend to have slightly higher elevations and fewer water bodies, reducing the risk of flooding and maximizing sun exposure. The gently sloping land in these directions also allows for optimal panel positioning to capture sunlight throughout the day. Additionally, the agricultural lands that are less productive or fallow could be repurposed for solar installations. This approach would minimize the impact on food production while utilizing available open spaces. The relatively sparse population density in the rural outskirts of Ashta also means that large-scale solar projects could be developed with minimal disruption to local communities. It's worth noting that while the immediate vicinity of rivers and streams might seem attractive due to their flatness, these areas should be approached with caution. Proximity to water bodies can increase humidity and the risk of flooding, potentially affecting the efficiency and longevity of solar equipment. Therefore, slightly elevated areas away from major water courses would be preferable for large-scale solar PV development in the region around Ashta.

India solar PV Stats as a country
