Modern solar design software enables EPCs to create accurate site layouts, shading models, and production estimates remotely. It cuts up to 80 percent of in-person site visits while improving proposal precision and customer confidence.
Let’s learn more.
For many EPCs, site visits are a necessary but costly part of their workflow. The solar site visit cost is not only about sending a team with measuring tools; it includes the total expense of travel, labor and administration.
An average site visit can easily cost $150 to $300 per project, according to solarreviews.com. When this multiplies across ten or more projects each week, EPCs spend around $1,500 to $3,000 weekly, which adds up to nearly $12,000 a month. That is money that could be invested in marketing, growth, or better client support, but instead, it gets consumed by logistics.
Time is another hidden cost. Each site visit involves scheduling, possible weather delays, and rescheduling when the client is unavailable. Sometimes, teams even need repeat visits due to redesigns or missed details during the first assessment.
Some EPCs report that almost one-third of site visits are repeats, caused by inaccurate data collection or new design requests. Each trip reduces profit margins and delays proposal delivery, which slows down client decisions.
The truth is that traditional site assessments simply do not scale well. As solar demand grows, EPCs need a smarter and faster solution. That is where solar design software comes in and transforms the entire process.
Imagine being able to analyze a customer’s property, assess roof angles, model shading, and simulate energy output without even leaving your desk. That is exactly what solar design automation makes possible.
Today’s leading tools use satellite imagery, LiDAR data, and 3D mapping to recreate real-world site conditions with impressive accuracy. They can automatically calculate tilt, azimuth, and roof slope to within a few inches, making manual data collection almost unnecessary.
Platforms like Arka360’s solar software take this a step further by capturing all design data in one unified workflow. You design once, and that same data automatically powers your proposal, bill of materials, and even your permit package. There is no duplication, no confusion, and no need for multiple site visits.
A small EPC in California shared that after adopting automated design tools, they were able to reduce on-site visits by 75 percent. Instead of spending days collecting roof details, they completed accurate designs within hours using remote modeling and cloud-based imagery.
This system works because the process is simple and intelligent. You upload the address, visualize the roof geometry, identify obstructions such as trees or vents, and optimize panel placement for maximum energy yield all inside one platform.
Remote design is not just convenient; it also eliminates redundant steps and dramatically increases precision.
It may sound surprising, but remote solar designs are often more accurate than manual site assessments. The main reason is consistency. Human measurements can vary depending on who is collecting the data, while software algorithms remain precise every time.
Traditional methods rely heavily on tape measures, ladders, and personal judgment. A single mistake in the roof angle or shading assessment can throw off the entire design. On the other hand, solar proposal accuracy achieved with software uses verified data sources:
According to sunbasedata.com, automated shade reports and AI-based performance simulations consistently outperform manual readings. When proposals use simulation-driven data, they align closely with the actual post-installation performance, which reduces the risk of underperformance and client complaints.
One EPC reported that before using digital tools, they saw a 10 percent deviation between predicted and actual energy output. After switching to automated software, that difference dropped to less than 3 percent.
That kind of precision builds trust with customers. When your proposal predicts energy performance accurately, you prove credibility even before installation begins.
Accurate remote design also means fewer change orders and smoother installations. When installers receive correct data from the start, they complete projects faster and with fewer on-site corrections.

Every minute saved and every unnecessary trip avoided directly impacts profitability. The ROI of solar design software can be clearly measured, and many EPCs experience returns within months of implementation.
Accurate and visually appealing proposals convert faster. Studies show that well-designed proposals can increase acceptance rates by 15 to 25 percent because they demonstrate reliability and professionalism.
Here’s a simple ROI example:
If your team creates 50 proposals a month and each avoided site visit saves $200, that translates to $10,000 saved every month or $120,000 per year.
Combine that with faster proposal delivery times from days to just a few hours and the productivity improvement becomes even more significant.
An EPC using Arka360 recently reported that by replacing manual CAD tools with Arka’s automated workflow, they cut their design cycle by 60 percent. What previously took five hours per design now takes less than two.
In simple terms, smarter proposals do not just improve design accuracy; they help your business grow faster and more profitably.
Switching from manual processes to digital design workflows may sound challenging, but it can be straightforward with a clear plan. Here is a simple step-by-step roadmap for adopting solar design software effectively:
Arka360 also provides dedicated onboarding support and training sessions so EPCs can start using digital tools effectively right away.
Once your team adjusts, remote design will become a natural part of your everyday workflow, saving time on every single project.
Here are some of the most common solar design software FAQs answered in simple terms:
Q1. How accurate are LiDAR-based roof measurements?
LiDAR data captures fine details with centimeter-level precision, often outperforming manual roof measurements.
Q2. Can software completely replace initial site surveys?
For most residential and small commercial projects, yes. Only complex or historical buildings typically require an in-person survey.
Q3. Does remote design meet local permitting standards?
Yes, high-quality software platforms generate permit-ready drawings and documentation that comply with utility and authority requirements.
Q4. How long does it take for a team to learn remote design tools?
Most teams become proficient within a few days. Platforms like Arka360 are intuitive and structured around familiar design steps.
Q5. Does image quality affect design accuracy?
Not significantly. Top platforms use multiple image sources and integrate ground-level data to maintain consistent accuracy.
