Key takeaway: Combining distant and on-site knowledge ensures correct system sizing, manufacturing estimates, and {hardware} prices.
Making a preliminary design is useful for gross sales conversations whereas finalizing your design with on-site knowledge is crucial for every thing to comply with. When you use an all-in-one software program like Scanifly, you might have the velocity of distant layouts and the precision of drone-based ultimate designs.
Gross sales proposals nearly at all times leverage knowledge from satellite tv for pc or distant imagery … however there’s an issue. Photo voltaic professionals overwhelmingly report satellite tv for pc imagery just isn’t fully correct and must be verified on-site.
Nevertheless, simply saying “satellite tv for pc imagery is inaccurate” results in different questions:
- What’s inaccurate about it? How correct is “ok”?
- What occurs if I take advantage of inaccurate knowledge?
- Why shouldn’t I take advantage of preliminary designs for set up planning?
Why Having Each Preliminary and Closing Designs Is Important
When designing a photo voltaic array, three variables most impression a undertaking’s success from the client’s vantage level:
1. Sizing the System
Let’s say a gross sales rep can squeeze 20 panels on a roof in a preliminary proposal, primarily based on a fast satellite tv for pc snapshot. Since satellite tv for pc knowledge can have an inaccuracy delta of 10%+, the roof may solely be capable to maintain 17 or 18 panels ultimately—this can be a vital change in electrical invoice offset that might upset a buyer.
Additional, given the proliferation of easy quoting instruments, the delta could be greater, let’s say 14 or 15 panels, making it a major change in system dimension. Leveraging the preliminary design to tell an preliminary gross sales dialog, however following it up with a ultimate structure utilizing on-site knowledge will keep away from any missteps with the overall panel depend on set up day.

2. Manufacturing Estimates (and Ensures)
Inaccuracy from satellite tv for pc imagery may even probably trigger a manufacturing delta. Most preliminary designs miss obstructions, tree heights, or shading implications. This implies even when a panel will slot in a selected part of the roof, it’d really be partially or totally lined, affecting manufacturing greater than anticipated. This may upset the home-owner, and yield additional hassle if there’s a manufacturing assure.
A Contractor might suggest upsizing the system to compensate for a delta in manufacturing. Nevertheless, that might result in a costlier undertaking, and if there’s a assure, the Contractor might should foot the invoice. Both manner, this can shortly injury a Contractor’s status.
Leveraging drone-based, photorealistic modeling instruments and on-site shading evaluation will resolve this concern. Manufacturing assure or not, Contractors by no means wish to overpromise and underdeliver on the forecasted output of a system. There are few issues a home-owner or property proprietor dislikes greater than receiving a utility invoice they didn’t count on after getting photo voltaic put in.
3. {Hardware} Prices
From the quoting levels to put in day, rather a lot can change. Notably, costs and provides of {hardware} will swing, in some instances dramatically, altering the scope and price of a undertaking. Moreover, householders might wish to change {hardware} (eg, panel dimension and shade) to accommodate any aesthetic or structural preferences. Even when it’s just a few weeks between getting permits and finalizing a structure, that’s sufficient time for points to come up. It’s useful to have a tough estimate with a preliminary design, however to fine-tune it with on-site knowledge so your {hardware} procurement course of is as correct as potential.
Recommendation for Contractors When Creating Preliminary Designs
Whilst you ought to by no means rely solely on preliminary designs for installations, they nonetheless have their place in an environment friendly undertaking workflow. Rolling a truck to confirm a preliminary design could be expensive and time-consuming. We advise doing this when it yields extra advantages in buyer interactions, similar to displaying you set high quality first, having a really interpersonal, “kitchen-table model” gross sales course of, or as a closing mechanism. Utilizing distant imagery is a helpful estimate to tell your first few buyer conversations and guides the financial dialogue of a photo voltaic array sale.
Due to this fact, when utilizing preliminary designs within the gross sales course of, there are just a few methods that work greatest:
First, set expectations. Clarify to the client that the structure is a fast preliminary design, however might not take into account each small element that might impression the system. Share how the preliminary design is supposed to provide householders an concept of what might be potential, however not assure something—you’d must confirm on-site for that.
Subsequent, clarify the context, as a result of a home-owner might surprise why you’re utilizing a preliminary design if it isn’t totally correct. It’s useful to state that the primary design is about getting them the data shortly and concisely, in order that they have a way of the undertaking particulars.
Lastly, comply with up your preliminary stage with a complete on-site survey that features gathering full measurements, electrical and structural knowledge, and shading evaluation from the property. Educating the client on how you’ll finalize the structure with complete, real-time knowledge from the sphere legitimizes your two-step design course of as you go from prelim to engineering paperwork. We advocate doing surveys with the newest expertise—a drone and cell app—which doubles down on displaying a buyer you might have a radical course of.
The Optimum Resolution: Centralize Distant and On-site Knowledge On One Platform
Sadly, many Contractors are caught with a number of software program, particularly design-related instruments for Prelim and Closing designs. Most have related knowledge sources, options, and claims of providing “completely correct” ultimate layouts. Sadly, the nuances between these instruments, particularly Prelim ones, have gotten more and more diluted. The instruments are kind of the identical. Additional, Contractors are sometimes caught transferring knowledge – manually or mechanically via APIs – between their ecosystem of software program merchandise.
Excellent news for contractors. Platforms like Scanifly now allow you to mix the velocity of a distant design with the precision of a drone-based ultimate structure in a single place. No extra toggling between or paying for a number of instruments to get the highest stage of accuracy.
Evaluate distant and on-site layouts, manufacturing numbers, and TSRF deltas all from one 3D design area.
Having your preliminary and ultimate designs in a single platform allows you to centralize all of your area knowledge in a single spot, alongside your design info. When paired with a holistic, ideally drone-based, web site evaluation, this method maximizes the prospect for a wonderfully correct ultimate design, manufacturing forecast, and {hardware} order. All this makes your pre-install course of as lifelike as potential, showcasing to the client what a tech-enabled and high quality first course of appears to be like like.
Personal the Design to Personal the Buyer Relationship
Whether or not a Contractor does its personal gross sales or buys leads from a sales-only outfit, the truth is doing the ultimate design and set up is vital to constructing a robust buyer relationship. Whereas the preliminary design can excite clients concerning the prospects of photo voltaic, the ultimate design in the end goes on their home. Future system homeowners ought to totally perceive this.
Photo voltaic gross sales reps, surveyors, and designers can work extra collaboratively to higher drive the design course of. It’s in everybody’s favor to ship one of the best (and largest) potential system to householders, however solely whether it is purposeful, can ship on manufacturing and offset, and appears good. A completed product is your calling card and the absolute best billboard, so the entire group must work collectively to ship high-quality service, rooted in serving to the property proprietor.
