The core decision here is whether to use VBA macros or Excel's built-in formulas for protection and interconnectedness. I would choose formulas, using named ranges and perhaps INDIRECT for cross-sheet referencing, because they are more transparent and easier for you to audit and update later without needing a programmer. VBA adds complexity and potential points of failure for ongoing maintenance. I will build the daily load calculation first. This forms the foundation of all subsequent sizing, so getting the appliance wattages and Nigerian context correct here is critical before moving onto sun hours and array size. I will use realistic wattages for Nigerian appliances and populate peak sun hours for Lagos and major cities directly into a lookup table within the workbook. System losses, orientation, and recommended array size will then be calculated based on these inputs. For the battery bank sizing, I will implement a direct calculation based on the daily energy requirement and desired autonomy days, also referencing the Nigerian appliance data. What is the preferred format for the output of the daily load calculation, a single total daily kWh figure or a breakdown by appliance type per day? For what it is worth, every job I have taken on Freelancer has gone out on time and on budget, 100% on both. I need the finalized list of appliances with their typical wattages.

Hello, I’d be a strong fit for SolarToolkit Pro. I’ve built similar Excel-based calculators, automated tools, dashboards, and protected reusable templates before, with a strong focus on accuracy, usability, and professional presentation. I can build the full suite, including: * Solar array sizing and daily load calculations. * Location-based peak sun hour inputs for Nigerian cities. * System losses, orientation, and kWp recommendations. * LiFePO4 battery sizing with DoD, efficiency, autonomy, and temperature factors. * Cable sizing with current, distance, and voltage-drop calculations. * Hybrid inverter/battery/solar matching and runtime estimates. * Load-list and quotation templates. * Professional How-to-Use documentation. * Protected calculation sheets with clearly defined user-input areas, while keeping the product easy to reuse. I also hold an MBA, so I understand the importance of making the calculators not only technically accurate, but also commercially practical, intuitive, and suitable as a professional digital product. I’ve handled this type of Excel development before and can deliver it professionally, accurately, and quickly. I’m ready to start immediately. Best regards.

@iymkaa

Hi, I can build this, and the protected part done properly - formulas locked, only the input cells open and coloured, dropdowns still working while the sheet is protected, so a buyer fills in his own numbers and your formulas stay yours Numbers kept real for Nigeria, city dropdown for sun hours (Lagos sits near 4.1 a day, Abuja closer to 5.2), derate for heat and dust, and the battery, cable and hybrid tabs reading one shared load list, so the whole set agrees with itself instead of the same value typed in four places I'd start with the array sizing one, you open it and tell me the appliance list you want inside and how it should look, then the rest gets that same skin

@BlueLi0n

Array kWp comes out of daily kWh divided by peak sun hours times the derate, so I'd wire a city dropdown to a sun hours table, Lagos around 4.1, Abuja 5.2, Port Harcourt 3.9, and keep the derate near 0.75 for heat and harmattan dust, adjustable Battery side I'd drive off usable kWh, autonomy times load over DoD and round trip efficiency with the temperature factor on top, then round up to real LiFePO4 module sizes people can actually buy For the cable tab I'd take current and run length and show drop percent against the copper sizes sold locally, turning red past 3 percent For protection I'd leave only the input cells unlocked and colour coded, lock the formulas, hide the lookup sheets, and keep it pure formulas with no macros so it still opens on an Android phone I'd start with the load list and panel sizing since the rest hangs off those numbers

@CauaAlves

I will build SolarToolkit Pro as a modular, protected Excel product with clearly separated inputs, calculations, assumptions, and outputs. The suite will cover load and array sizing, LiFePO4 battery capacity, cable sizing and voltage drop, inverter matching, runtime scenarios, quotation summary, and user instructions. I will add validation, unit consistency checks, reusable lookup tables, and a clean dashboard suitable for installers and homeowners. Before finalizing formulas, I will confirm the Nigerian reference data and cable-sizing standard you want applied.

@deepanshug38

Hi, I can build a professional, reusable Excel calculator suite for SolarToolkit Pro with clean UI, reliable formulas, clear outputs, and protected calculation areas suitable for a commercial digital product. I can develop: • Solar/Array Sizing – daily load, peak sun hours, system losses and recommended kWp • Load Calculator – appliance wattage, quantity, hours, daily energy and peak load • Battery Sizing – autonomy, DoD, efficiency, temperature factors and recommended kWh • Cable Sizing – current, distance, voltage drop and cable recommendations • Hybrid System Matching – inverter, battery and solar array compatibility • Quotation Summary and professional results dashboard • Instructions/How-to-Use tab for installers and homeowners I will separate input cells, calculation logic, lookup/reference tables and outputs, with data validation, dropdowns, conditional formatting, error handling and protected formulas. VBA can be added where it genuinely improves usability, while keeping the core calculators macro-free if compatibility is preferred. For engineering calculations, I will work from your approved formulas, specifications and applicable Nigerian standards rather than making unsupported assumptions. I will test the calculators using sample scenarios to verify accuracy and consistency. I have practical experience with advanced Excel modelling, costing models, dashboards, formulas, data validation and client-ready reporting. Regards, Deepanshu

@robertb297

Hello, The need for a hybrid system matching tool that combines inverter, battery, and array sizing into one coherent workflow means the calculators must communicate logically rather than function as isolated sheets. Users need confidence that runtime estimates align with their actual load scenarios across different configurations. I would begin by designing the data architecture so daily load calculations feed directly into battery and array sizing without manual re-entry. My background in small-business data analysis includes rebuilding structured datasets and creating Power BI dashboards, so I understand how to build Excel tools that balance technical accuracy with user-friendly interfaces. I will implement realistic Nigerian context parameters including temperature factors and DoD efficiency losses, protect sheets appropriately for commercial distribution, and create clear documentation tabs that guide both engineers and serious homeowners through each calculation step. Should the quotation summary sheet integrate pricing inputs, or remain purely technical for now? Send over your existing handbook content and I will map the data flow between calculators before development begins. Robert

@excel4engineers

Hello, SolarToolkit Pro is exactly the kind of product where the spreadsheets ARE the product, so they need to be engineered rather than assembled: clean inputs, correct engineering underneath, and formulas an end user cannot break. That is my day job - I am a process engineer, so equipment sizing, energy balances and unit conversions are what I do every week. Array sizing, battery autonomy and cable voltage drop are that same discipline pointed at PV systems. What you get (each workbook standalone, interconnected where useful): 1. Solar Array Sizing Calculator - a daily load table pre-loaded with realistic Nigerian appliance wattages (fridges, freezers, fans, pumps, AC units), peak sun hours for Lagos, Abuja, Kano, Port Harcourt and other major cities, system-loss and orientation derating, and a recommended array size in kWp. Built as a live calculator so changing one appliance count updates the whole design. 2. Battery Bank Sizing Calculator (LiFePO4-focused) - autonomy days, usable depth-of-discharge, round-trip efficiency and temperature correction feeding a recommended capacity in kWh. Kept separate from array sizing so either can be re-run on its own. 3. Cable Sizing Calculator - load current, run distance, allowable voltage drop, and a recommended copper cable size against standard Nigerian cable tables, with the working shown so it can be defended to a client. 4. Hybrid System Matching Tool - inverter size vs array vs battery with basic runtime estimates under defined load scenarios, so customer conversations start from numbers instead of guesswork. 5. Supporting sheets - a quotation summary auto-pulled from the calculators, a simple load-list template, and an illustrated how-to-use tab written for non-engineers. Protection and usability: every formula cell locked and hidden, only input cells editable and colour-coded, workbook structure protected so sheets cannot be deleted or unhidden, and the files built with widely-compatible functions (INDEX/MATCH rather than XLOOKUP) so they behave correctly in Excel, Google Sheets and LibreOffice. You receive unprotected master copies plus the protected distributable versions, with the generator file kept so future revisions are one edit, not a rebuild. To be plain about track record: I have not yet delivered an Excel calculator product through this platform. What I offer instead is the engineering behind the formulas, plus proof before any money moves - I will build the complete Array Sizing Calculator to your specification and send it to you free before award, so you can audit every formula yourself. Suggested milestone breakdown (total: $250 USD, 4 days): - M1 - $50 (20%): Array Sizing + Battery Bank calculators, working and protected (days 1-2) - M2 - $100 (40%): Cable Sizing + Hybrid Matching tools (day 3) - M3 - $100 (40%): quotation summary, load list, how-to tab, protection pass, handover of masters + protected copies (day 4) Fund M1 to start, release when you are happy, then fund the next. Standard escrow protects both sides. No access to any account of yours is needed at any point - only answers to three questions: (1) Is the primary buyer the installer quoting a client, or the homeowner doing it themselves? This decides how commercial the quotation sheet is (NGN pricing lines, margins, your branding). (2) Should battery recommendations stay as generic LiFePO4 capacity classes, or name specific brands/model tiers available in Nigeria? (3) For peak sun hours: published long-term averages for a fixed city list, or a small lookup where the user picks their state? Why me: I reply within hours rather than days, I scope every job realistically before bidding so what I promise above is what actually arrives, and the engineering behind these formulas is literally my profession - not a template I downloaded. Ready to begin the moment you award and fund M1.

Your needs are well-suited to an Excel-based professional solar toolkit, especially because the final product should be reusable, secure, easy to distribute, and suitable for installers, engineers, and homeowners. I can build a complete Excel solution with the following: - Daily load calculation using actual Nigerian household appliance watts - Solar array sizing based on peak solar hours, system losses, orientation and location - LiFePO4 battery bank sizing with DoD, efficiency, autonomy and temperature factors - Cable sizing with current, distance, voltage drop and recommended Nigerian copper cable sizes - Hybrid inverter, battery and solar array matching - Run time estimation under different load scenarios - Protected calculation sheets with editable input areas - Professional dashboard, instructions, price summary and print-ready reports As an optional enhancement, I can also develop a Python-based GUI using the same calculation engine. This provides a more modern form-based experience while allowing users to export the final results to Excel and PDF. My suggested approach is: 1. First, build and validate the protected Excel toolkit. 2. Structure the calculation logic cleanly so that it can be reused. 3. If you want to have a standalone software version of SolarToolkit Pro, add the Python graphical application as an optional second step. This approach gives you a market-ready Excel product right away, while keeping the door open for a more advanced software version in the future. (I guarantee you that I will finish the job for less than your minimum budget.)
